UPS uninterruptible power supply
Product introduction
Uninterruptible power supply (UPS) is a system device that connects batteries (mostly lead-acid maintenance-free batteries) to the host and converts direct current into mains power through module circuits such as the host inverter. It is mainly used to provide a stable and uninterrupted power supply to a single computer, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc., to ensure the uninterrupted operation of these equipment and instruments, and to prevent computer data loss, telephone communication network interruption or instrument loss of control.
Product application
Uninterruptible power supplies are widely used in: Mining, aerospace, industry, communications, 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 energy conversion equipment, control equipment and emergency protection Systems, personal computers and other fields.
