Gmr-32b Phase Controller Manual

Search for a specific to a certain motor type.

Evaluates amplitude deviations. If line voltages breach pre-configured upper limits (surges) or lower limits (brownouts), the internal relay trips to safely isolate sensitive control logic.

Automatically trips if the phase order (L1, L2, L3 or R, S, T) is incorrect, preventing motors from running in reverse.

: Check the tightness of all electrical connections, as thermal cycling can cause screws to loosen over time. gmr-32b phase controller manual

If the phase sequence is reversed, the output relay will not activate.

Disconnect the primary load for safety during initial voltage verification.

: It features an easy-to-read LED display system that indicates the exact status or fault type, allowing for rapid troubleshooting. Compact Installation : At roughly mm, it fits easily onto standard HT35 DIN rails or can be screw-mounted using M4 holes. Manual Highlights & Technical Specs Specification Rated Voltage is less than or equal to 460 VAC (suitable for 380V standard) Connection Wire Insulated copper wire (1.0~2.5mm) Mounting Options HT35 DIN rail or direct screw mounting Primary Use Cases Air compressors, oil pumps, cranes, and HVAC units Pros and Cons High Reliability Search for a specific to a certain motor type

Complete Technical Manual and Calibration Guide for the GMR-32B Phase Controller

Connect the relay contact terminals in series with the magnetic contactor coil of your motor or load. Normally Open (NO): Closes when power is normal.

: If the "ON" LED is lit along with other indicator LEDs (often marked R, L, or Y), it signals a phase sequence error phase failure Automatically trips if the phase order (L1, L2,

Regular maintenance is also essential to ensure optimal performance and extend the lifespan of the device:

: Maintain a minimum of 50mm clearance around the heatsink for natural convection. 2. Technical Specifications Specification Input Supply Voltage 200V – 480V AC, 3-Phase, 50/60 Hz Current Rating 32 Amps Continuous Control Modes Phase-Angle Triggering / Zero-Cross Burst Fire Analog Command Signals 4-20mA, 0-10V DC, 1-5V DC, or 10kΩ Potentiometer Auxiliary Power Supply 24V DC / 100mA Enclosure Rating IP20 (Panel Mount) 3. Installation and Dimensions

Sets the base power level when the control signal is at its lowest value (e.g., 4mA or 0V). Turn clockwise to pre-heat elements.

The GMR-32B front panel usually includes indicator lights that show the status of the power supply.
