ZJ-ATSAC220-100A power switching device is a disturbance-free power switching product specially developed by Shanghai Zhijin Electric Technology Co., Ltd. for power plant customers.

Advantages over previous power switching devices:

1: Realize seamless automatic switching between two power sources

2: Automatic identification of overvoltage and undervoltage

3: Super strong anti-impact current capability, large overload margin

4: Using imported transistors with extremely small internal resistance, the heating coefficient is smaller

5: Intelligent temperature control system, long service life

   At present, it has been successfully put into operation on the thermal power supply of millions of units! It is the only solution to the problem of power switching loss in power plants. At this stage, old units use mechanical power switching devices, which cannot meet the high sensitivity loads such as relays, solenoid valves, water pump contactors, and PLCs. On the surface, it appears that two power sources supply power to the load through a mechanical switching device, but they do not play a fundamental role. Switching under crisis conditions, the case of unit shutdown caused by load loss is common. Therefore, the use of high-strength transistor switching can quickly complete the switching action within half a cycle, and the entire process is completed between 4-8 milliseconds. Using Shanghai Zhijin's transistor switching can truly achieve disturbance-free switching, which makes the two power sources really work. To work.
