Three-Phase SCR Power Regulator Modules

Three-phase SCR power regulator modules — also referred to as three-phase thyristor power regulators — provide precise and balanced AC power regulation for three-phase resistive heating loads — controlling each phase independently using SCR (thyristor) technology to ensure uniform power distribution and stable heating performance.

Unlike transformer-based voltage regulators, these SCR modules provide fully isolated, solid-state power regulation with no mechanical contacts — faster response, higher precision, and longer service life.

Standard 380V three-phase AC input, rated current 10A to 200A. Compact module design for OEM panels and control cabinet integration. DC output available on request. Custom current ratings and configurations available.

External heat sink required for all models — forced air cooling recommended for high current ratings.
