1. UPS power supply is a system equipment that connects the battery (mostly lead-acid maintenance free battery) to the host and converts DC power into mains power through module circuits such as the host inverter.
2.UPS power supply is mainly used to provide stable and uninterrupted power supply to a single computer, computer network system, or other power electronic equipment such as solenoid valves, pressure transmitters, etc.
3.When the mains power input is normal, the UPS stabilizes the mains power and supplies it to the load for use. At this time, the UPS power supply is an AC voltage stabilizer, and the UPS also charges the internal battery.
4.When the mains power is interrupted (accident power outage), UPS immediately supplies 220V AC power from the battery to the load through the method of inverter switching conversion, so as to maintain the normal operation of the load and protect the software and hardware of the load from damage. UPS power equipment usually provides protection against high or low voltage.
