The GMR-32B utilizes advanced microprocessor-controlled phase-angle firing to regulate AC power. By precisely clipping the AC waveform, it delivers smooth, infinitely variable power to resistive and inductive loads. Key Specifications 110V – 480V AC (Self-sensing, 50/60 Hz)
The unit generates significant heat during operation. Do not block the heatsink.
Trips when voltage exceeds or falls below safe thresholds. Installation & Wiring gmr-32b phase controller manual
Proper installation and setup of the GMR-32B phase controller are crucial for ensuring safe and efficient operation. The following steps should be followed:
| Specification | GMR-32B / Smart Series Value | | :--- | :--- | | | 200-500VAC (Standard), up to 690VAC (Smart Series) | | Frequency | 50 / 60 Hz | | Rated Control Circuit Voltage | Three-phase 220V, 380V, 400V, 415V, 440V, 460V | | Relay Contact Capacity | 5A at 250VAC (resistive load) | | Voltage Measurement Accuracy | ±1% of reading | | Over/Under Voltage Set Point | Adjustable approx. ±15% of nominal voltage | | Over/Under Voltage Hysteresis | 7V (prevents relay chatter) | | Voltage Imbalance Trip Level | >10% or >20% (model dependent) | | Response Time (Trip Delay) | Phase Loss: 1s / Phase Sequence: 0.1s / Over/Under Voltage: 7s / Imbalance: 5s | | Reset Mode | Automatic (restores function when fault clears) | Do not block the heatsink
While you should always consult the specific physical manual included with your unit, general wiring follows this pattern: L1, L2, L3: Connect these terminals to the three incoming power phases. Relay Contacts:
The GMR-32B features a clear set of indicator LEDs for quick and accurate fault diagnosis, making it easier to locate the source of a problem without complex tools. The following steps should be followed: | Specification
The (also known as a Phase Sequence Relay or Protector) is an industrial safety device designed to monitor three-phase power systems. Its primary role is to protect motors and machinery from damage caused by electrical faults like phase reversal, loss, or voltage imbalances. Technical Specifications
