  • Service & Support


50 years of experience are infused in the Thyro-PX®  series’ design and functionality. The SCR power controller is available in single-, dual-, and three-phase units, supports voltages from 184 to 690 V and 16 to 2900 A, and offers superior interface options. Integrate modes seamlessly with a 2.8-inch, LED Thyro-Touch display. And enable efficient system parameters, loading, and storage (up to six process parameters) via an on-board SD-card. Thyro-PX power controller is ideally suited for your transformer and resistive loads for glass, metal, and ceramic manufacturing. It is optimal for heating elements in electric furnaces.


  • Minimize peak kVA demand via MoSi and TAKT load management
