科士达UPS不间断电源怎么安装？

科士达UPS电源安装。首先，看你购买的UPS不间断电源是什么样的机型。从机型上确认用户是否可以进行自行安装。

目前，科士达UPS电源有几种机型划分：

小型标机：1-10KVA的机型 延时5-15分钟

长效机：外接电池 根据用户实际所需配置电池组

单相机型：输入输出220V的1-15KVA的机型

三相机型：输入输出380V的6KVA以上的三相机型

根据以上机型进行确认用户是否可以自行进行安装。一般情况下小型的标机用户都可以进行直接安装。在安装前用户详细阅读相关说明书。

长效机机型的科士达UPS电源安装则看用户实际电力知识。因为，其中涉及到外置电池的安装部分。一般不建议用户自己安装。

单相机型与长效机上面所说一样!其实长效机包含了单相机型与三相机型。

三相机型，由于是三相工业用电。也不建议用户自己进行安装。科士达UPS电源电池组安装有一定风险，需专业的电工人员进行安装。

科士达UPS电源安装，不建议用户自己进行安装。可以联系相应的科士达UPS电源厂家工程师，由其提供安装服务。如果，用户有一定电工知识的，可在科士达UPS电源厂家人员指导下进行安装。

Costa UPS power installation. First, look at the UPS Uninterruptible Power Supply you purchased. Verify whether the user can install it by himself from the model.

Currently, there are several types of UCSD UPS power supply:
Minitype marking machine: 1-10KVA model delay 5-15 minutes
Long-acting machine: external batteries are equipped with battery packs according to users'actual needs
Single Camera Model: 1-15KVA Model with 220V Input and Output
Three-phase model: three-phase model with input and output of 380V and more than 6KVA
According to the above models, confirm whether users can install by themselves. In general, small-scale camera users can be installed directly. Before installation, the user reads the relevant instructions in detail.
Installation of UPS power supply for long-term machine models depends on users'actual power knowledge. Because it involves the installation of external batteries. Usually, users are not recommended to install it by themselves.
The single camera model is the same as the long-acting machine mentioned above. In fact, the long-acting machine includes the single camera model and the three-phase model.
Three-phase model, because it is three-phase industrial electricity. It is also not recommended that users install themselves. Installation of UPS battery pack in Costa needs professional electrician to install.
Costa UPS power installation, do not recommend users to install their own. You can contact the engineer of the corresponding Kosta UPS power supply factory to provide installation services. If the user has certain electrical knowledge, it can be installed under the guidance of the staff of the UPS power supply manufacturer in Costa.

巡检人员应每天记录科士达UPS电源的运行情况，电压、电流值，发现问题及时处理;检查各信号灯工作是否正常;保持蓄电池外部清洁;蓄电池组运行状态检查运行温升：蓄电池在浮充状态时不发热，若发现个别电池有发热现象应立即检查原因，及时处理，若发现整组电池发热,首先应检查电池的运行状态(强充或放电均有一定的温升),是否浮充电流过大或电池组发生外部微短路等现象，发现问题应及时处理。

检查蓄电池组的连接点，接触是否严密，有无氧化，并涂以凡士林油。

在外观检查时，做到:

a.是否有机械性损坏，设备内是否有小动物尸体;

b.设备内部是否落有导电性的污垢或灰尘;

c.堆积的灰尘是否影响了散热。

科士达UPS电源定期维护：

每月测量一次蓄电池组的电压及单体电池的电压,每只电池电压应在1.35-1.4V，若发现电池的电压偏低或不均匀,及时处理

模拟市电失电试验:有意识让蓄电池向直流母线放电，动作正常后，立即送交流电源,蓄电池应能自动切断放电回路,该试验的操作时间不超过30分钟，由于机组及发电运行极为重要不可间断，模拟失电试验具体时间最好安排在停机时间，且规定每月一次。

每年对蓄电池核对容量一次，对蓄电池核对容量有二个目的：

a. 了解蓄电池的实际运行容量;

b. 对蓄电池组进行一次活化，使电池容量均匀，

每年对市电电源切换装置进行校验，采取从进线侧分别断开电源一和电源二的方法，检验进线切换模块动作的准确性，确保切换动作无误。

每年对科士达UPS电源所有切换模块进行定期检验，采取从电源进线侧分别断开市电一、市电二、旁路电源的方法，在检验切换模块切换功能是否动作准确的同时，也检验逆变器功能是否正常。(操作时必须按照步骤操作，在市电和旁路都断开的情况下，输出的电源一直有压为正常)

Inspectors should record the operation status of UPS power supply, voltage and current values, find out problems and deal with them in time; check whether the signal lights are working properly; keep the outside of the battery clean; check the operating temperature of the battery group: the battery does not heat when it is in floating charge state; if it is found that individual batteries have heating phenomenon, it should be checked immediately, handled promptly, and if it is found that the whole group is clean. Battery heating, first of all, should check the operation status of the battery (strong charge or discharge have a certain temperature rise), whether the floating charge current is too large or the battery has external micro-short circuit phenomenon, and find out that the problem should be dealt with in time.
Check the connection points of the batteries, whether the contacts are tight, whether there is oxidation or not, and coat them with Vaseline oil.
In the appearance inspection, do:
A. Whether there is mechanical damage and whether there are small animal corpses in the equipment;
B. Is there any conductive dirt or dust inside the equipment?
C. Does the accumulated dust affect the heat dissipation?
COSTAR UPS Power Supply Regular Maintenance:
Measure the voltage of the battery group and the voltage of the single battery once a month. The voltage of each battery should be 1.35-1.4V. If it is found that the voltage of the battery is low or uneven, it should be handled in time.
Simulated city power loss test: consciously let the battery discharge to the DC bus, and send the AC power immediately after normal operation. The battery should be able to automatically cut off the discharge circuit. The operation time of the test is not more than 30 minutes. Because the unit and the power generation operation are extremely important and uninterruptible, the specific time of the simulated power loss test should be arranged in the downtime, and it is stipulated that once a month.
The checking capacity of storage battery is checked once a year. There are two purposes for checking capacity of storage battery:
A. Understanding the actual operating capacity of the battery;
B. Activate the battery pack once to make the battery capacity uniform.
Every year, the municipal power supply switching device is checked. The method of disconnecting the power supply one and two from the input side is adopted to check the accuracy of the operation of the input switching module, so as to ensure that the switching action is correct.
Every year, all switching modules of Kosta UPS power supply are checked periodically. The method of disconnecting the power supply from the input side of the power supply is adopted to check whether the switching function of the switching module is accurate or not. At the same time, the function of the inverters is normal. (The operation must be carried out step by step. The output power supply is always under normal voltage when both the power supply and the bypass are disconnected.)

应定期对科士达UPS电源控制系统作如下检查：

a. 检查控制的显示模块显示与运行情况是否一致，显示无黑屏及乱码，如遇此现象尽快更换显示模块。

b. 检查显示控制屏是否有异常声响，如有报警及其他异常现象及时处理。

C. 检查显示控制屏操作按钮，确认各按钮功能正常，切换检查有关功能和参数，如遇异常及时上报处理。

科士达UPS电源应避免频繁的开机关机，最好长时间处于开机状态。确实需要关机的，应在关机后5秒钟以上再开机。

检查电池组至科士达UPS电源导线是否老化，老化的应及时更换相同载流面积的导线，尽量避免增加不必要的导线长度。

检查市电是否一直处于正常的供电之中，如果示电一直处于正常工作中，科士达UPS电源就没有工作的机会，其电池就有可能长时间浮充而损坏。因此，对长时间不用的科士达UPS电源要定时进行人为的强制工作，这样可以活化电池，还可以检验科士达UPS电源是否处于正常状态。

检查通信是否正常、数据是否准确，异常情况及时予处理。

检查免维护式电池，经常检查溶液的比重及电液量是否合格。

要确保所配接的负载容量不超过科士达UPS电源容量的三分之二。

储能电池的工作全部是在浮充状态的，要定期充电放电，间隔2～3个月放电一次为宜，至少应每年进行一次放电。放电前应先对电池组进行均衡充电，以达全组电池的均衡。

一般每季度应彻底清洁一次。其次就是在除尘时，检查各连接件和插接件有无松动和接触不牢的情况。

当科士达UPS电源电池系统出现故障时，查明原因，分清是负载还是UPS电源系统;是主机还是电池组，逐步排查解决。

The following checks should be made regularly for the UPS power supply control system of Kosta:
A. Check whether the display module of the control is consistent with the operation condition, and show that there is no black screen and scrambling code. If this happens, replace the display module as soon as possible.
B. Check to see if there is any abnormal sound on the control screen, and deal with the alarm and other abnormal phenomena in time.
C. Check the operation buttons of the display control panel, confirm that the functions of each button are normal, switch and check the relevant functions and parameters, and report to the processing in time if abnormal.
Corstal UPS power supply should avoid frequent switching on, preferably for a long time in the boot state. If it really needs to be shut down, it should be restarted more than 5 seconds after shutdown.
Check whether the battery pack to Kosta UPS power supply conductor is aging. The same current-carrying area conductor should be replaced in time to avoid increasing unnecessary conductor length.
Check whether the municipal power supply has been in normal power supply. If the indicator has been in normal work, the Kosta UPS power supply will not have the opportunity to work, and its batteries may be damaged by floating charge for a long time. Therefore, the long-term unused Corstal UPS power supply should be regularly mandatory work, so as to activate the battery, but also to check whether the Corstal UPS power supply is in normal state.
Check whether the communication is normal, the data is accurate, and the abnormal situation should be handled in time.
Check the maintenance-free batteries, check the proportion of solution and whether the electro-hydraulic quantity is qualified.
Make sure that the load capacity allocated does not exceed two-thirds of the capacity of Kosta UPS power supply.
All the work of energy storage batteries is in floating charge state. It is advisable to charge and discharge periodically at intervals of 2 to 3 months, or at least once a year. Battery batteries should be charged equally before discharging, so as to achieve the balance of the whole batteries.
Generally, it should be thoroughly cleaned once a quarter. Secondly, when removing dust, check whether the connectors and sockets are loose or not.
When the battery system of Kosta UPS power supply fails, find out the reason, distinguish load or UPS power supply system, host or battery, and gradually solve the problem.

二、科士达UPS电源系统的选用

酒店内重要的智能化系统全部采用科士达UPS电源集中供电的方式，以保证在市电断电时酒店的业务能够正常运行。需要为楼宇自控系统、闭路监控系统、防盗报警系统、计算机网络系统、程控交换机系统等几大系统统一供电。由于选用的科士达UPS电源数量较多，功率较大，因此需要在具体实施时进行地面承重测试。

工业作为实体经济的主体，涵括了如制造、冶金、石化、钢铁、煤炭、电力等在内的诸多基础性行业和支柱型产业，在国民经济中占有重要的地位。工业科士达UPS电源系统作为工业企业正常生产和运转的基础，为大量先进的工业生产设备和信息系统的安全、持续运行提供着可靠的电力保护，在这些领域发挥着非常关键的作用。

随着信息技术的普及和“两化融合”的深入推进，我国工业自动化水平得到了更大提高，大量的高端、智能生产设备和信息系统的应用也日趋广泛，从而对事关工业生产安全、支撑智能设备和信息系统平稳运行的UPS系统的建设应用，也提出了更高要求。对此，业界主流的动力设备和一体化解决方案供应商之一，厂家能源结合工业应用场合的特点，针对科士达UPS电源在工业领域的应用要点进行了科学分析，并就如何建立操作灵活、安全可靠、智能管理的科士达UPS电源系统，为工业用户做出了解答。

随着信息技术在工业领域生产、运营、管理等各个环节的深入应用，以及高端、精密设备的大量应用，工业领域对供电质量提出了越来越高的要求，不仅要求供电的连续性要得到可靠保障，而且对于电源的纯净度更是有着特殊要求。但是，在工业领域电力应用中，供电质量往往受到各种因素的影响，例如，电网污染、自然界的雷电、大容量的电动机启动、功率因数补偿电容器的切换等等，都会直接影响到供电质量，造成电压波动、脉冲干扰乃至供电中断等问题。在此背景下，科士达UPS电源以其稳压精度高、能够不间断向负载提供纯净电能的优势广泛地应用于工业领域，为工业生产、管理提供了可靠的电力保障。

需要指出的是，工业用科士达UPS电源与一般布置在数据机房内，洁净度、温湿度等运行环境条件能够得到有效保障的商用UPS相比，具有很大的不同。在实际应用中，工业用科士达UPS电源需要面对工业生产场合中常见的灰尘、酸雾、高温、噪音、干燥或过湿等各种恶劣的环境条件，以及电波干扰、浪涌冲击、峰值下限等电网污染。同时，工业用科士达UPS电源源所连接的负载多为电感性负载、电容性负载、波动和高峰值冲击性负载等，对电流的冲击大。基于工业生产特殊的环境场合，工业用科士达UPS电源需要在可靠性、可用性、适应性，以及防护等级、带载能力等多个方面具有远远高于商业科士达UPS电源的性能表现，来应对工业应用恶劣的物理环境、供电环境和负载环境的考验。

科士达UPS电源的工作方式

1、科士达UPS电源正常运行方式

科士达UPS电源系统的供电原理是当市电正常时，机器会将市电的交流电转换为直流电，而后对电池充电，以备电力中断时使用;这里跟各位强调的是不断电系统并不是停电时才会动作，像是遇到电压过低或过高、瞬间突波等，足以影响设备正常运转的电力品质时，不断电系统均会动作，提供设备稳定且干净的电力。

当市电正常供电时，市电经滤波回路后，分为两个回路同时动作，其一是经由充电回路对电池组充电，另一个则是经整流回路，作为逆变器的输入，再经过逆变器的转换提供电力给负载使用;由此可知，在线式不断电系统的输出完全由逆变器来供应，因此不论市电电力品质如何，其输出均是稳定而不受任何影响。

2、科士达UPS电源电池工作方式

一旦市电发生异常时，将储存于电池中的直流电转换为交流电，此时逆变器的输入改由电池组来供应，逆变器持续提供电力，供给负载继续使用，达到不断电的功能。UPS不间断电源系统的电力来源是电池，而电池的容量是有限的，因此不断电系统不会像市电一般无限制的供应，所以不论多大容量的不断电系统，在其满载的的状态下，其所供电的时间必定有限，若要延长放电时间，须购买长时间型不断电系统。

3、旁路运行方式

当在线式科士达UPS电源超载、旁路命令(手动或自动)、逆变器过热或机器故障，UPS一般将逆变输出转为旁路输出，即由市电直接供电。由于旁路时，UPS输出频率相位需与市电频率相位相同，因而采用锁相同步技术确保UPS输出与市电同步。旁路开关双向可控硅并联工作方式，解决了旁路切换时间问题，真正做到了不间断切换，控制电路复杂，一般应用在中大功率UPS上。如果在过载时，必须人为减少负载，否则旁路短路器会自动切断输出。

4、科士达UPS电源旁路维护方式

当科士达UPS电源进行检修时，通过手动旁路保证负载设备的正常供电，当维修操作完成后，重新启动UPS，UPS转为正常运行。极低的维护率，MTTR为15万小时，极大地提高科士达UPS电源可用性。

正确使用和维护科士达UPS电源,不但能使科士达UPS电源有效地发挥作用,而且还能延长其使用寿命。

1、对存放重要信息的计算机或停电损失较大的设备要进行重点保护

2、不能长期按照额定功率来运行科士达UPS电源，最好是保持60%-80%负荷率。

4、感性负载一般由工频科士达UPS电源供电;后备式的不适用。

5、应确保科士达UPS电源的配电柜使用的是空气开关

7、让蓄电池在合适的温度环境中工作，25℃最佳。

Selection of UPS Power Supply System in Costa
In order to ensure the normal operation of the hotel business when the power is cut off in the city, all the important intelligent systems in the hotel adopt the way of centralized power supply from the UPS power supply of Costa. It is necessary to provide unified power supply for building automation system, closed circuit monitoring system, anti-theft alarm system, computer network system, program-controlled switch system and other major systems. Because of the large number of UPS power supply and the high power, it is necessary to carry out ground load-bearing test in the specific implementation.
As the main body of the real economy, industry covers many basic industries and pillar industries, such as manufacturing, metallurgy, petrochemical, iron and steel, coal, electricity and so on. It occupies an important position in the national economy. As the basis of normal production and operation of industrial enterprises, the UPS power supply system of Industrial Costa provides reliable power protection for the safe and continuous operation of a large number of advanced industrial production equipment and information systems, and plays a key role in these fields.
With the popularization of information technology and the deepening promotion of "integration of two modernizations", the level of industrial automation in China has been greatly improved, and a large number of high-end, intelligent production equipment and information systems have been increasingly widely used, thus putting forward higher requirements for the construction and application of UPS system, which is related to the safety of industrial production and supports the smooth operation of intelligent equipment and information systems. In this regard, one of the mainstream power equipment and integrated solutions suppliers in the industry, manufacturers of energy combined with the characteristics of industrial application occasions, scientific analysis was made on the application points of Corstal UPS power supply in the industrial field, and how to establish a flexible, safe and reliable, intelligent management Corstal UPS power supply system was given to industrial users.
With the in-depth application of information technology in the production, operation, management and other aspects of the industrial field, as well as the extensive application of high-end and precision equipment, the industrial field has put forward higher and higher requirements for the quality of power supply. It requires not only the continuity of power supply to be reliably guaranteed, but also the purity of power supply to have special requirements. However, in industrial power applications, the quality of power supply is often affected by various factors, such as grid pollution, lightning in nature, large-capacity motor start-up, power factor compensation capacitor switching and so on, which will directly affect the quality of power supply, resulting in voltage fluctuation, pulse interference and even power supply interruption. In this context, Kosta UPS power supply is widely used in the industrial field with its advantages of high voltage stabilization accuracy and uninterrupted supply of pure electric energy to the load, providing reliable power guarantee for industrial production and management.
It should be pointed out that the industrial Corstal UPS power supply is quite different from the commercial UPS, which is generally arranged in the data room and can be effectively guaranteed by the operating environment such as cleanliness, temperature and humidity. In practical application, industrial Corstal UPS power supply needs to face various adverse environmental conditions, such as dust, acid fog, high temperature, noise, drying or excessive humidity, as well as power grid pollution, such as radio interference, surge impact, peak and lower limit. At the same time, most of the loads connected by industrial Corstal UPS power supply are inductive load, capacitive load, fluctuating load and high peak impact load, which have great impact on current. Based on the special environment of industrial production, industrial Corstal UPS power supply needs to have much higher performance than commercial Corstal UPS power supply in reliability, availability, adaptability, protection level, load capacity and other aspects to cope with the test of harsh physical environment, power supply environment and load environment of industrial application.
COSTAR UPS POWER SUPPLY WORKING MODE
1. Normal operation mode of Kosta UPS power supply
The power supply principle of Kosta UPS power supply system is that when the municipal power is normal, the machine will convert the AC power of the municipal power into DC power, and then charge the batteries for use in case of power interruption. It is emphasized here that the uninterrupted power supply system will not operate when the power is cut off, such as when the voltage is too low or too high, instantaneous surge, etc., which will affect the power quality of the normal operation of the equipment. The power-off system operates to provide stable and clean power for the equipment.
When the municipal power supply is normal, the municipal power is divided into two circuits after filtering circuit, one is charging the battery through charging circuit, the other is charging the battery through rectifying circuit, as the input of the inverters, and then converting the inverters to provide power for the load to use; thus, the output of the on-line continuous power system is entirely supplied by the inverters, regardless of the municipal power supply. The output of force quality is stable without any influence.
2. Operation mode of UPS battery in Costa
Once the city electricity is abnormal, the DC stored in the battery is converted to AC. At this time, the input of the inverters is supplied by the battery pack. The inverters continue to provide power and supply the load to continue to use, so as to achieve the function of continuous power supply. The power source of UPS UPS UPS is batteries, and the capacity of batteries is limited. Therefore, UPS will not be supplied as unrestricted as municipal power supply. Therefore, no matter how large the capacity of UPS is, its power supply time is bound to be limited when it is fully loaded. To prolong the discharge time, it is necessary to purchase a long-term continuous power supply system.
3. Bypass operation mode
When the on-line Corstal UPS power supply is overloaded, bypass command (manual or automatic), inverter overheating or machine failure, UPS generally converts the inverter output to bypass output, that is, direct power supply from the municipal electricity. Due to bypass, the output frequency and phase of UPS need to be compared with that of UPS.

另外在组装蓄电池时,要千万注意不能将容量不同、出厂品牌不同的电池混合使用,这样会让科士达UPS电源的实际使用效果大打折扣。

8、所选科士达UPS电源的容量应该与保护对象的功率相匹配

9、在选购时要学会检测科士达UPS电源

为了检验选购的科士达UPS电源是否符合实际需要,在选购UPS之后,还必须通过现场测试来确认一下所选的UPS是否与实际需要相符。测试时主要检查的内容包括对UPS的启动检查、报警和自动关机检查、电池供电/充电时间检查、市电/电池切换点检查等。检测UPS能否对计算机提供断电保护简单的方法就是突然拔掉UPS的电源插头,如果计算机能继续正常运行,则认为UPS能胜任保护工作。另外用户还应重视对UPS输出能力和可靠性的考察,因为UPS输出能力的各项性能指标,都是可以量化的可靠性指标。在同等运行条件下,效率高、输出电流峰值系数大、过载能力强的UPS,其可靠性必然高。

10、正确对科士达UPS电源进行操作

例如不能随便对其进行开关机操作,在打开科士达UPS电源时,应先接通科士达UPS电源输入开关,然后再打开逆变器的开关;在关机时,应该先关闭逆变器的开关,然后在断开输入开关。当不需要UPS工作时,最好将其关闭,因为如果科士达UPS电源工作完而不关电源,一旦遇到突然停电,那么UPS就有可能一直处于工作状态,即使不带负载,也会消耗少量的电池能量。这样长时间消耗能量又不及时充电,最后电池的容量就会枯竭而损坏,从而引起UPS故障。另外,为了防止雷击引起科士达UPS电源短路或者产生火灾事故,一定要把UPS电源放在通风散热良好的地方,并确保科士达UPS电源能有效的接地。

11、科士达UPS电源要定期检查电池的端电压

为了能及时了解科士达UPS电源的工作状态,应该每半年测量一次单体电池的端电压(额定值为12V)。如果电压差超过1V就应该使用均衡的恒压限流充电,否则只能更换电池。如果当地长期不停电,必须定期人为中断供电,使UPS带负载放电，这样可以延长电池的寿命。长期没有断过电,无法得知电池是否正常,而实际上一旦断电,有可能提供很短的放电时间甚至根本放不出电,原因就是蓄电池长期处于浮充的结果。

12、不要频繁开关科士达UPS电源

由于频繁开关科士达UPS电源会产生尖峰电流，这种电流可能会让UPS内部的保险丝熔断，从而损坏UPS，因此在开关机之间至少要有6s以上的时间间隔。

In addition, when assembling batteries, we should pay attention not to mix batteries with different capacities and different brands, which will greatly reduce the actual use effect of Corstal UPS power supply.
8. The capacity of the selected Corstal UPS power supply should match the power of the protected object.
9. Learn to test Kosta UPS power supply when choosing and purchasing
In order to verify whether the selected Corstal UPS power supply meets the actual needs, after purchasing UPS, field tests must be carried out to verify whether the selected UPS is in line with the actual needs. The main inspections include start-up inspection, alarm and automatic shutdown inspection of UPS, battery power supply/charging time inspection, city power/battery switching point inspection, etc. A simple way to test whether UPS can provide power-off protection for computers is to suddenly unplug the power plug of UPS. If the computer can continue to operate normally, UPS is considered to be competent for protection. In addition, users should also pay attention to the inspection of UPS output capability and reliability, because the performance indicators of UPS output capability are quantifiable reliability indicators. Under the same operating conditions, UPS with high efficiency, high peak coefficient of output current and strong overload capability will inevitably have high reliability.
10. Correct operation of Corstal UPS power supply
For example, it can not be switched on or off at will. When turning on the Kosta UPS power supply, the input switch of the Kosta UPS power supply should be switched on first, and then the inverter switch should be turned on; when turning off, the inverter switch should be turned off first, and then the input switch should be disconnected. When UPS is not required to work, it is best to turn it off, because if the Kosta UPS power supply is finished and not turned off, once a sudden power failure occurs, UPS will probably remain in working condition, even without load, it will consume a small amount of battery energy. This will consume energy for a long time without charging in time, and eventually the capacity of the battery will be exhausted and damaged, thus causing UPS failure. In addition, in order to prevent the short circuit or fire accident caused by lightning strike, it is necessary to put UPS power supply in a well ventilated and heat dissipation place, and ensure that the UPS power supply of Costa can be effectively grounded.
11. Corstal UPS power supply should check the terminal voltage of batteries regularly.
In order to know the working status of the Corstal UPS power supply in time, the terminal voltage of the single battery (rated at 12V) should be measured every six months. If the voltage difference exceeds 1V, a balanced constant voltage current limiting charge should be used, otherwise the battery can only be replaced. If the local power supply is not maintained for a long time, it must be interrupted periodically to discharge UPS with load, so as to prolong the battery life. It is impossible to know whether the battery is normal or not without power cut for a long time. In fact, once the power cut off, it may provide a very short discharge time or even no power at all. The reason is that the battery is in floating charge for a long time.
12. Don't switch Kosta UPS frequently
Because frequent switching of Kosta UPS power supply can produce spike current, this current may cause fuses inside the UPS to fuse, thereby damaging the UPS, so there should be at least 6 s interval between the switches.
