The GMR-32B Phase Controller is a high-performance industrial power management unit designed for precise SCR (Silicon Controlled Rectifier) firing control. It regulates electrical power delivered to resistive or inductive loads by varying the phase angle of the AC voltage waveform.
Keep ambient temperature between 0°C and 50°C. Humidity: Maintain below 85% RH without condensation.

Disconnect all power sources before attempting installation. Ensure proper grounding to prevent electrical shock. Do not exceed the rated current and voltage limits. Install in a well-ventilated, dust-free environment.
The installation of the GMR-32B is designed to be straightforward, with a compact size that saves space in electrical panels. Pre-Installation Check gmr-32b phase controller manual
Prevents damage caused by low voltage which increases heat and current draw. 3. Basic Wiring & Operation
Wire the internal relay output contacts in series with your master contactor's control coil.
These terminals receive the command signals from your PLC, Temperature Controller, or manual potentiometer.
