Tips: What is UPS?
UPS is an uninterruptible power supply that contains energy storage devices. It is mainly used to provide uninterrupted power supply to some equipment which requires high stability of power supply. The system equipment that converts direct current into mains electricity through host inverter and other module circuits. 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.
When the mains input is normal, UPS supplies the mains voltage regulator to the load. At this time, UPS is an alternating current voltage regulator, and it also charges the battery inside the machine. When the mains is interrupted (accidental power failure), the UPS will immediately supply 220V AC power to the load by switching the dc power of the battery through the method of inverter conversion, so that the load can maintain normal work and protect the software and hardware of the load from damage. UPS equipment usually provides protection against high or low voltage.
Uninterruptible power supply is widely used in: aerospace, industry, communications, defense, hospitals, computer terminal, network server, data storage equipment, emergency lighting system, railway, transport, power plants, substations, fire security alarm system, wireless communication system, solar energy is stored energy conversion equipment, control equipment and emergency protection system, personal computers, and other fields.
