  • Understanding UPS UPS

     

    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

  • UPS uninterruptible power supply common failure analysis

     

    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

  • UPS working principle

     

    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

  • SK616 technical parameters

     

    Brand: Shank Model: SK-616 / SK-313Input voltage: 15V / 1A Storage capacity: 13200MA / 6600MAOutput voltage: 5V 9V 12V (2A) 15V 24V (1A)Safety protection: overheating protection / short circuit protection / overvoltage protection

  • Precautions for uninterruptible power supply during discharge

     

    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

  • UPS uninterruptible power supply engineering installation technology

     

    In order to strengthen the standardized management and construction process requirements for UPS field installation and construction, to ensure that UPS power supply equipment operates reliably and is easy to maintain for design requirements. In order to protect the safety of the construction personnel, the correct construction regulations and processes must be followed.The specifications described in this article apply to the site installation and construction of new, expanded, and rebuilt UPS
