The air conditioning relay is a multi-function three-phase three-wire power system or a three-phase power equipment detection and protection instrument. It integrates three-phase voltage display, over-voltage protection, under-voltage protection, phase loss protection (phase failure protection), three-phase voltage unbalance protection, phase sequence protection (wrong phase protection), and uses powerful microprocessor chips and Non-volatile memory technology can replace the three-phase voltmeter function. The display adopts high-definition ultra-wide temperature Chinese liquid crystal, which has the features of complete functions, stable performance, intuitive display and convenient operation.

The air conditioning relay can display the three-phase power supply voltage in real time, and can provide the alarm output form by providing the alarm output form in the form of relay output when the power supply has over voltage, under voltage, phase loss, three-phase voltage imbalance, and fault equal failure. The contact control signal of the protection circuit action output acts as an alarm and protection.
