Compact Thyristor Power Controller

Compact thyristor power controllers (SCR power controllers) deliver precise AC power regulation in a space-saving design — ideal for OEM panels, small control cabinets, and limited-space industrial heating applications. Based on SCR (thyristor) technology, these controllers accurately adjust output power using phase angle, zero-crossing, or burst firing control modes.

Suitable for resistive, inductive, and capacitive loads. Single-phase configurations available on request. RS485 Modbus RTU communication supported. Custom voltage, current, and control configurations available for OEM projects.
