When S1-4 = ON and an external current transformer (CT) is installed on the load wire, the GMR32B adjusts firing angle to maintain load current proportional to the setpoint, compensating for input voltage fluctuations.
Minimum 2500V AC between control circuit and power circuit. gmr32b phase controller manual
The GMR32B series is built with high-quality components and complies with major international safety standards: When S1-4 = ON and an external current
💡 : Always ensure the power is completely disconnected before wiring or inspecting the controller to prevent electric shock. GMR-32B Phase controller, 300-400V 50/60HZ - JIEFENG 300-400V 50/60HZ - JIEFENG 0-10V DC
0-10V DC, 4-20mA current loop, or manual potentiometer (typically 10kΩ).
: Wire these to an external indicator lamp or alarm system to instantly broadcast a fault condition status. Diagnostics & Troubleshooting
