UPS power supply

Uninterruptible power supply (UPS) is a system equipment that connects the storage battery (mostly lead-acid maintenance-free storage battery) with the host computer, and converts DC power into commercial power through module circuits such as host inverter. It 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 and pressure transmitters, to ensure the uninterrupted operation of these equipment and instruments, and to prevent computer data loss, telephone communication network interruption or instrument out of control.
Uninterruptible power supply is widely used in mines, aerospace, industry, communication, national defense, hospitals, computer business terminals, network servers, network equipment, data storage equipment, emergency lighting systems, railways, shipping, transportation, power plants, substations, nuclear power plants, fire safety alarm systems, wireless communication systems, program-controlled switches, mobile communications, solar energy storage conversion equipment, control equipment and its emergency protection system, and personal computers.
