The E110070 is a thyristor-based power controller from Optron that uses phase-angle firing to regulate AC power delivery to resistive heating loads. By varying the conduction angle within each AC half-cycle, it provides infinitely adjustable power output with smooth, proportional control — ideal for radiant heaters and thermal processing equipment where precise temperature regulation and low electromagnetic interference are required.

What makes phase-angle control suitable for radiant heaters?

Phase-angle firing adjusts power continuously rather than in discrete on/off bursts, eliminating the thermal cycling and flicker associated with zero-cross (burst-fire) control. For radiant heating applications, this means consistent element temperature, longer heater life, and finer process control — particularly important in thermoforming, plastic welding, and industrial drying operations.
