Is there an off-line UPS?
3. The UPS automatically switches between power supply and battery power to ensure uninterrupted power supply to the load. The computer equipment and communication equipment do not allow the power to be intermittent (switch time 0ms), so it should be confirmed that you need the UPS switch time is how much.
2. When the grid voltage is abnormal (undervoltage, overvoltage, power down, interference, etc.) UPS inverter converts the DC power of the battery pack into AC power to maintain the power supply to the load.
Uninterruptible power supply: UPS [UninterruptiblePowerSystem (orSupply)]: is the battery pack, inverter and other circuits, can be in the power grid to provide AC power when the power supply equipment.
UPS has the following basic functions:
1. When the grid voltage is normal, the mains voltage is regulated by the UPS after the power supply. The UPS itself is a good AC voltage regulator. At the same time, it also charges the battery and stores the reserve energy.
