Thyristor Power Controller

Thyristor power controllers (SCR power controllers) provide precise and stable AC power regulation for industrial heating, temperature control, and process automation — with optional DC output available on request. Based on SCR (thyristor) technology, these controllers accurately adjust output power using phase angle, zero-cross, or burst firing control modes to match process requirements.

Suitable for resistive loads including electric heaters, furnaces, ovens, and kilns. Three-phase and single-phase configurations available. Digital control interface supported. OEM, multi-zone, and custom AC/DC configurations available for project requirements.
