Install a cooling fan or ensure the heatsink fins are oriented vertically to allow for natural convection. C. Harmonic Noise and Overloading
Thermal cycling (heating and cooling) can loosen screw terminals over time. gmr32b phase controller manual hot
Most digital variants of the GMR series feature LED indicators for thermal protection: Install a cooling fan or ensure the heatsink
Typically 4-20mA, 0-10V DC, or Potentiometer. gmr32b phase controller manual hot
Resistive (heaters) or Inductive (transformers/motors).
Running the GMR32B at its absolute limit (32A) in a high-temperature environment will lead to thermal runaway.
The is a robust controller, but it is not "set and forget." High heat is almost always a symptom of poor thermal dissipation or loose electrical junctions. Ensure your thermal paste is fresh and your cabinet is breathing, and the unit should return to stable operation.
