The power supply situation of manufacturing plants is complex, especially the manufacturing industry has many types of loads, from IT equipment to manufacturing equipment, the demand for power supply is not the same. As the types and quantity of production equipment increase, once power supply problems occur, such as sudden power failure, instantaneous undervoltage, overvoltage, waveform distortion and frequency drift, etc., it will cause the early investment to be scrapped, and cause equipment damage, which will bring to the enterprise. loss. Therefore, many industrial production equipment are equipped with UPS power supplies. Industrial UPS power supplies are designed with high stability, high reliability, and super anti-overload ability according to the application characteristics of the industrial field. It eliminates the harsh physical environment and electrical Various problems such as complex environment and high load capacity requirements, and also have humanized management functions to provide users with highly reliable power protection.
