Three-Phase SCR Voltage Regulator Modules are compact thyristor-based controllers designed for precise and balanced AC power regulation of three-phase resistive heating loads. By controlling each phase independently, they ensure stable heating performance and uniform power distribution.

Key Features & Applications

Supports standard 380V three-phase AC input with current ratings from 10A to 200A, with optional customized DC output. The compact module design allows easy OEM and control cabinet integration, providing precise SCR power control for industrial heating systems. External heat sinks are required, with forced air cooling recommended for higher current ratings.
