Misunderstanding of APC Schneider UPS power supply maintenance

As an important uninterrupted emergency power supply, APC Schneider UPS is widely used in data center, computer room system and other important places. APC Schneider UPS power supply is affected by environment and other factors, so it needs irregular maintenance to avoid failure. Many misunderstandings will occur during maintenance, resulting in some failures and losses. Today, APC Schneider UPS power supply manufacturer will introduce in detail:

1、 High frequency machine APC Schneider UPS power supply is a new technology product, there is no high-power products

In the previous impression, APC Schneider UPS belonged to low availability, low reliability and "high energy and low efficiency". However, the selection of APC Schneider UPS is in the transition period. In the past, APC Schneider UPS used to consume a lot of energy in several aspects, and it also has a great impact on the reliability of APC Schneider ups. However, the high-frequency APC Schneider UPS can solve such problems, and its efficiency can reach 95% under load.

The so-called APC Schneider ups of high-frequency machine refers to the APC Schneider ups with input and output circuits working above 20kHz and without output transformer circuit. Compared with the 90% operation efficiency of traditional power frequency machine APC Schneider UPS, the advantages of high frequency machine APC Schneider ups are more obvious. High frequency APC Schneider UPS not only has the technical specifications of power frequency machine APC Schneider UPS, but also has higher performance and index, which is beyond the power frequency APC Schneider ups. Therefore, in the selection of APC Schneider UPS, high-frequency APC Schneider ups will be the development trend in the future.

2、 APC Schneider UPS power supply can be lightning proof

In the data center, the power supply system belongs to alternating current, which can be divided into two situations after coming in from the power grid. If it is very important, the data center must be equipped with generators. From AC power to data center, the first problem to be solved is lightning protection. After AC comes in, before entering APC Schneider UPS, level III lightning protection must be completed before power distribution cabinet. The first level of lightning protection should reduce the lightning surge voltage above 7000 V to below 4000 V, the second level to below 2500 V, the third level to below 1500 V, and then to 1000 V through the filter of APC Schneider UPS input circuit. At this time, APC Schneider UPS itself can be used.

When purchasing APC Schneider UPS, some users will ask "how many levels of lightning protection can this APC Schneider UPS provide?". This shows that some users have such misunderstanding - APC Schneider UPS has lightning protection function. In fact, the surge current of three-level lightning protection can reach 8000 a, which is beyond the endurance of any type of APC Schneider ups. The third level lightning protection must be completed on the input distribution cabinet of APC Schneider UPS front end.

3、 APC Schneider UPS power supply maintenance free battery does not need "maintenance"

In the power supply system of data center, the battery life is the shortest, but it is the equipment with the most faults. Many users think that maintenance free batteries do not need maintenance, which is a big misunderstanding. The full name of maintenance free battery is lead-acid valve regulated maintenance free battery. "Maintenance free" refers to that it does not need to measure the specific gravity of the battery, and does not need to add battery water.
