Three-Phase SCR Voltage Regulator Modules
Product Overview
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. Using SCR technology to control each phase independently, these modules ensure uniform power distribution, stable heating performance, and improved process control.
Ideal for 380V three-phase systems, with rated currents from 10A to 200A, these modules are perfect for OEM panels, compact control cabinets, and modular heating systems where space efficiency and reliable operation are essential. DC output versions can be customized for special applications.
For safe and stable operation, external heat sinks are required, and forced air cooling is recommended for higher current ratings.
