    UPS - Uninterruptible Power Supply
    UPS ( Uninterruptible Power System ), or Uninterruptible Power Supply, is a constant voltage and constant frequency uninterruptible power supply with energy storage device and inverter as its main component. It is mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the mains input is normal, UPS supplies the mains voltage to the load for use after stabilizing the mains voltage. At this time, UPS is an AC mains voltage stabilizer, and it also charges the battery in the machine. When the mains supply is interrupted ( accident power failure ), UPS immediately supplies 220 V AC power to the load by means of inverter conversion, so that the load can maintain normal operation and protect the load's software and hardware from damage. UPS equipment usually provides protection for both high and low voltages.
    UPS is a third generation frequency pure online intelligent UPS developed with new digital technology to meet the reliability requirements of power supply in China's power grid environment and network monitoring and network system, medical system, etc. and to overcome the increasingly bad power supply grid environment caused by centralized power supply in medium and large computer network systems. The DC power supply is a device for maintaining a steady current in the circuit. [ 2 ] such as dry battery, storage battery, DC generator, etc. UPS and DC power supply are important power supply guarantee equipment for enterprises. Traditional maintenance management includes: ① routine inspection appearance, regular replacement of vulnerable parts such as batteries, filter capacitors and fans, battery activation during overhaul, etc. ( 2 ) to reform or adopt replacement equipment and use advanced tools to test battery performance. This kind of management mode has high investment cost for enterprises, heavy workload for maintenance personnel, difficulty in mastering equipment operation status and key data in real time, and low equipment accident prevention capability. The implementation of online maintenance management can avoid the shortcomings of traditional methods and obtain good benefits.
