How to Improve UPS Power Supply Efficiency

1. Start-up and shut-down sequence when using UPS power supply

The correct sequence of power-on and power-off should be first to turn on UPS to supply power to UPS, then turn on each load, so as to avoid damage caused by instantaneous current surge when UPS starts. In reverse order, you should do the opposite before closing the load and ultimately closing UPS. When the main power supply is interrupted by UPS, you should save your own data and data as soon as possible, and then turn off the computer. Otherwise, the use of UPS power supply may lead to excessive discharge of UPS, thus shortening the service life of UPS.

2. UPS power supply has the first charging skill

After purchasing UPS power supply, UPS should be plugged into 220V power supply network and charged 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 is not used for a long time. The battery should be fully charged 24 hours every 2 to 3 months, and the UPS power supply should be in the inverter for 2 to 3 minutes to ensure the normal service life of the battery. When UPS power is connected to the main power supply, the battery pack will be charged. Press the power button for more than one second and turn on the inverter.

3. UPS power supply can not be idle for a long time

Overdischarge of batteries and long-term open circuit of batteries do not allow the increase of internal resistance of batteries and deteriorate their charging and discharging performance. For long-term unused UPS power supply, please use the charging circuit in the machine to charge the UPS power supply 12 hours before restarting the power supply. For standby UPS price, it is better to let UPS power into the inverter every other month. Activate the battery by working for 2 to 3 minutes. In addition, the charging current of batteries must be strictly controlled so that it does not exceed the allowable charging current of batteries. Because excessive charging current can shorten battery life.
