GMR-32B Phase Controller Manual — Quick Guide & Tips

What it is

The GMR-32B Phase Controller is an industrial device used to control AC power by adjusting the phase angle of the input waveform. It’s typically used for reactive load control, motor soft-starting, heater power regulation, and other applications requiring smooth voltage control.

4.1 Power Section

  • L1, L2, L3: Input three-phase supply (through circuit breaker).
  • U, V, W: Output to three-phase load (heater, motor, transformer).
  • Ground: Connect to terminal marked PE (Protective Earth).

Route your raw three-phase power lines (L1, L2, L3 or R, S, T) directly to the sample input terminals on the controller. gmr-32b phase controller manual

is a three-phase monitoring relay (often referred to as a phase sequence protector or phase controller) designed to protect industrial equipment like air compressors, pumps, and central air conditioning units.

The GMR-32B Phase Controller (also known as a phase monitoring or sequence relay) is a protection device for three-phase systems. It is primarily used to detect faults such as overvoltage, undervoltage, phase loss, and incorrect phase sequence. L1, L2, L3: Input three-phase supply (through circuit

Operating Conditions: Works in temperatures from -10°C to +55°C and relative humidity of 45%–85%.

Front-panel layout & controls

  • Power indicator: Shows unit is powered.
  • Phase/angle knob or digital setpoint: Adjusts conduction angle to vary output voltage.
  • Control input terminal block: For 0–10 V, potentiometer, or external control signals.
  • Load terminals (L, N, output): Connect supply and controlled load per wiring diagram.
  • Status LEDs: Indicate firing status, fault conditions, and run/stop state.
