Gmr-32b Phase Controller Manual Jun 2026

The GMR-32B is solid-state and requires no scheduled maintenance. However, to ensure long-term reliability, you should periodically:

115V AC / 230V AC or 24V DC auxiliary power (model specific, ±10% tolerance). Line Frequency Auto-Tracking: 45 Hz to 65 Hz. Control Input Options (Selectable): 4–20 mA DC (Input impedance: 250 Ωcap omega 0–10 V DC (Input impedance: 100 k Ωcap omega 0–5 V DC Manual Potentiometer (10 k Ωcap omega

Keep the controller away from high-temperature elements like SCR heatsinks, line reactors, and braking resistors. 3. Wiring and Terminal Configurations gmr-32b phase controller manual

What are you protecting? (e.g., air compressor, water pump, crane)

Secure the relay on a standard DIN rail within an enclosed control panel to avoid vibration. Main Circuit Wiring (Input): Connect the three-phase power lines ( L1, L2, L3 ) to the input terminals. The GMR-32B is solid-state and requires no scheduled

A detailed wiring diagram specific to your control circuit should always be referred to from an official manufacturer's manual, as available from your supplier.

This manual covers the standard GMR-32B as well as its enhanced variant, the , which offers superior performance through a high-reliability microcontroller and an advanced Smart platform. Control Input Options (Selectable): 4–20 mA DC (Input

Ensures that the sequence of incoming lines matches the specified clockwise rotation (
