This article mainly introduces what is the use of the high voltage control box in the computer. It is very detailed and has a certain reference value. Friends who are interested must read it!

The function of the high voltage control box: to control the connection or disconnection of the main power line of the controller, which helps to protect the safety of the circuit and the controller. Its structure is the same as the traditional relay, one coil and one normally open switch, and the large current is controlled by small current.

When the condenser is seriously fouled, the fan is faulty, the cooling air volume is insufficient, the refrigerant is excessive, and there is air or other non-condensable gas in the system, it will produce excessive exhaust pressure and reduce the working efficiency and refrigeration effect of the air conditioner. Serious damage to the compressor. Therefore, air conditioners are generally equipped with high-voltage controllers. The high voltage controller is installed on the exhaust pipe and can automatically cut off the main circuit of the air conditioner through the control circuit board when the exhaust pressure is too high.

In the household air conditioner, the cabinet machine needs to weld the high pressure controller in order to limit and protect the high pressure pressure of the system. The setting value of the working pressure of the high pressure controller should be lower than the design pressure on the high pressure side of the refrigeration cycle.
