  • Knowledge points of UPS power supply in weak current system room

     

    Foreword:The UPS system is usually used in the computer room of the intelligent system . So what exactly does the UPS system mean and how to choose it?text:First, the meaning of UPS uninterruptible power supplyMeaning: UPS is an uninterruptible power supply. It is a system device that connects the battery 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 single computer, computer network system or other power electr

  • Ten basic functions of UPS uninterruptible power supply

     

    1) Voltage stability --- The mains voltage is easily affected by the quality of the power transmission line. The user voltage near the substation is higher by about 130 ~ 120V, and the user voltage farther from the substation is lower by about 100 ~ 90V. If the voltage is too high or too low, the life of the user equipment will be shortened, and the equipment will be burned in severe cases. The use of online UPS can provide a stable voltage power supply, and the voltage change is less than 2V, w

  • What are the advantages of installing a UPS

     

    Prevents power failures of critical equipment, ensuring system reliability and data integrity. As a separate set of equipment, UPS is the most effective measure to ensure system safety and uptime.When a lightning strike occurs: Lightning can cause overvoltage. In this case, the power company usually cuts off the power supply, resulting in system power interruption. The power supply of electronic equipment such as computers cannot be reliably guaranteed. This may cause the hard disk to crash, and

  • Do you know some of the causes of the short circuit of the external battery of the UPS?

     

    How is the UPS uninterruptible power supply external battery short circuit caused? UPS battery short circuit means that the positive and negative electrode groups inside the lead battery are connected. The short-circuit phenomenon of lead batteries is mainly manifested in the following aspects:    (1) The open circuit voltage is low, and the closed circuit voltage (discharge) quickly reaches the termination voltage.    (2) When the large current is discharged, the terminal voltage drops

  • UPS battery charge and discharge knowledge

     

    Mastering the correct method of UPS battery use and good maintenance of the UPS battery can enhance the performance and service life of the UPS battery, so how can the UPS battery be charged and discharged?About charging1. When the UPS floats and charges, please use the charging voltage of 2.275V / single cell (the set value at 20 ℃) for constant voltage charging or a current below 0.002CA for constant current charging. When the temperature is below 0 ° C or above 40 ° C, it is necessary to m

  • What is the role of UPS uninterruptible power supply?

     

    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
