Understand UPS uninterruptible power supply -module power sharing UPS uninterruptible power supply combined with new power technology, UPS uninterruptible power supply module power supply, the internal resistance of each power supply module is slightly different, and the output voltage may not be completely the same. Down Shank UPS briefly introduces the module power sharing of UPS uninterruptible power supply.What is the role of UPS uninterruptible power supply?1. Output impedance method, also

UPS is an uninterruptible power supply . It is a system device that connects storage batteries (mostly lead-acid maintenance-free storage batteries) to the host and converts DC power to mains power through module circuits such as the host inverter. It is mainly used to provide a stable, uninterrupted power supply to a single computer, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc. When the mains power input is normal, the UPS supp

Due to the aging of the UPS system in a substation , a phase-to-phase short circuit occurred. The fault current caused a fire in the UPS power screen, further caused AC string DC, and the breakdown of the varistor in the measurement and control device led to multi-point grounding of the DC system, eventually leading to power loss in the background monitoring system and remote communication.This was a more serious accident last September. Therefore , the importance of the UPS system is evident. L

First, the UPS uninterruptible power supply (hereinafter referred to as UPS) has a low voltage, but after charging for a long time, the UPS voltage still cannot be charged.Failure analysis: Judging from the phenomenon as UPS or charging circuit failure, you can check as follows:1. Check whether the input and output voltage of the charging circuit is stable;2, the charging circuit when the input is normal, the output is not normal, and then measuring the battery cut off, if not normal compared to

Regarding the working principle of UPS, many people should have a vague concept, it is not very clear, what is the specific working principle. And for users who use UPS, it is necessary to understand how it works. Today, I will introduce the knowledge about UPS working principle in detail here.The working principle of UPS uninterruptible power supply is simple and simple, and it is not difficult to say. Let ’s take Shank Power as an example to briefly talk about its working principle:AC-DC conv

Today, I bring to my friends the knowledge about UPS uninterruptible power supply (hereinafter referred to as UPS) maintenance. UPS in daily use, only a regular basis to extend the life of the UPS UPS discharge can generallyspeaking, UPS power supply battery charge and discharge at least once every three months, how can discharge the UPS allowed to dothe greatest strength How about it? Now, let's talk to you about the precautions during the charging and discharging process. When discharging
