      How can Shante UPS power supply be used reasonably to maximize power?

      Shanterups power supply is a kind of energy storage equipment, UPS protects our data from harm. So it is very important to protect UPS power supply. Next, I will introduce how to use the power supply rationally to maximize the power of Xiashan Special ups.



      1. Reasonable selection of device orientation



      A good location of the device is very important. It is necessary for the place where UPS is placed to have outstanding ventilation function. It is necessary to keep away from water, flammable gases and corrosives. The ambient temperature should be between 0 and 40 C. If UPS is disassembled and installed at low temperature, there may be a phenomenon of water droplet condensation. Once the ambient temperature exceeds 25 degrees, the battery life will be reduced by half for every 10 degrees increase. Currently, UPS batteries are usually unprotected sealed lead-acid batteries with a planned life of 5 years. Power supply should not be placed side-wise, and the intake and outlet holes should be kept clear; when the load is connected with UPS power supply, the load should be closed first, then wiring, and then turn over the load one by one, so as to prevent rational loads such as electric power and photocopiers from being connected to UPS, so as to avoid damage. When UPS is connected to a special socket with over-current protection equipment, the power socket used should be connected to the protection ground end; whether the input power line penetrates into the market outlet or not, the output of UPS may be live. In order to make UPS output-free, it is necessary to turn off the switch first, and then cancel the power supply.



      2. Start-up and shut-down sequence when using UPS



      Accurate turn-on sequence should first turn on UPS to supply power to it, and then turn on each load, so as to avoid the harm caused by the instantaneous current impact on UPS at start-up. On the contrary, the turn-off sequence should first close each load and finally close UPS. When power supply is stopped by UPS, the data and materials of UPS should be reserved and the computer should be closed. Otherwise, the operation with UPS power supply may cause excessive discharge of UPS, and then shorten the service life of UPS.



      3. Tips for initial charging



      After the new UPS power supply is installed, UPS should be pierced into 220V city power grid, charging for at least 12 hours to ensure that the battery is fully charged. Otherwise, the actual available capacity of the battery will be much lower than the nominal capacity of the battery. If UPS power supply is not used for a long time. It should be started 24 hours every 2-3 months to make the battery fully charged and keep the UPS power supply in the operation condition of inverters for 2-3 minutes to ensure the normal life of the battery. Once the UPS power supply is connected to the market, the battery is charged at the beginning, and the inverter is turned on by pressing the boot button for more than 1 second.



      4. Avoid overload and use UPS



      When using UPS, we should also calculate the size of the load, to avoid overload or too small load, too large load will make UPS work in overload condition for a long time and then shorten the service life of UPS; if the load is too small, the operation circuit of UPS will work in abnormal condition for a long time, which is also bound to be harmful to UPS.



      Reasonable load should be controlled between 50% and 80%. Practice has proved that the output load control of UPS at 60% is the best and the reliability is the best. When UPS is overloaded or the inverter fails, it will turn to bypass mode. At this moment, UPS has no backup function. The power used by the load is supplied directly through the power system.



      5. Battery Balanced Charging Tips



      Many VRLA batteries used in UPS power supply are called unprotected batteries from the beginning, which gives users a misunderstanding as if they are used and need no protection at all. In this misleading way, many users have not been protected and handled since they installed batteries. Batteries in UPS power supply should be charged equally when excessive discharge causes the terminal voltage to be lower than the regular calibration voltage of the battery. For 12V small sealed lead-acid batteries, the discharge calibration voltage is 10.5V; for 24V batteries, the discharge end voltage is 21V; for 96V batteries, the discharge calibration voltage is 85V. The battery was not charged in time after discharge; the unused battery was shelved for a long time. The city power is cut off, the floating batteries are connected, and nearly half of the capacity of the batteries is released. 8. Don't use diesel generators



      It is not suitable to supply power by diesel generator, because its frequency often changes abruptly and unsteadily, which affects the normal operation of UPS.



      6. Real-time monitoring



      At present, intelligent UPS has some operational functions such as communication with microcomputers and program control. By installing the corresponding software on the computer and connecting UPS through serial/parallel ports, and running the program, the computer can communicate with UPS. Usually it has functions of information inquiry, parameter setting, timekeeping setting, automatic shutdown and alarm. Like Winpower. Then the UPS can be connected to the computer through special serial port control cable, and then communicated with RS232 and RS485 protocol, which can complete the function of automatic shutdown when UPS has no market power input and low power consumption. And it can monitor multiple UPS connected on multiple serial ports together. In the meantime, through RS232 protocol, a serial port can only connect one UPS, and through RS485 protocol, a serial port can connect 256 UPS at most.



      7. UPS can't be shelved for a long time



      The excessive discharge of the battery and the long open-circuit shelf of the battery can increase the internal resistance of the battery and deteriorate its charging and discharging functions. For long-term shelved UPS power supply, before starting from scratch, charge the charging circuit in UPS power supply applicator for 12 hours before loading. For backup UPS power supply, it is best to keep UPS power supply in the inverter condition for 2-3 minutes every other month to activate the battery. In addition, it is also necessary to strictly control the charging current of the battery and not exceed the maximum charging current promised by the battery. Because excessive charging current will shorten the life of the battery.
