SCR Power Regulators — Thyristor Power Controllers
SCR (thyristor) power regulators provide stepless power control for resistive heating loads by phase-angle or zero-cross firing of thyristors. Rated 10–2000 A for single-phase and three-phase loads, they regulate power to electric heaters, furnaces and drying ovens with fast response and high efficiency.

- Frequently Asked Questions
What is an SCR power regulator?
An SCR (thyristor) power regulator controls the power delivered to a resistive load by varying the conduction angle (phase-angle) or switching cycles (zero-cross), giving stepless regulation.
Phase-angle or zero-cross?
Phase-angle suits loads needing fast fine control; zero-cross reduces harmonics and EMI for resistive heating.
