GMR-32B Phase Controller (often branded as ) is a three-phase power monitoring relay designed to protect industrial equipment like air compressors, motors, and central air conditioning systems. It identifies critical electrical faults—such as phase reversal or voltage spikes—and cuts power to prevent motor burnout or equipment damage. AliExpress Core Protection Functions
Swap any two input wires; if the red LED activates, the sensor is working correctly.
If the controller is "tripping" unexpectedly or failing to engage: Check Connections:
Here is the distilled installation and calibration process as documented in the patched guide.
The GMR-32B acts as a "vigilant guardian" by monitoring the order of electrical phases in a three-phase system. It is specifically engineered to detect:
