Description

FC36M | 230V 3-Phase Dual Mode Thyristor Driver (c/w DIN Housing)

The FC36M 230V Dual Mode Firing Board with DIN Housing is a microprocessor-based three-phase thyristor driver designed for reliable SCR (thyristor) control in industrial power control systems. Housed in a robust DIN rail enclosure, it provides easy installation within electrical control panels while delivering accurate phase-angle and burst-fire firing for resistive and inductive loads.

Designed for seamless integration into power control assemblies, the FC36M eliminates the need for external phasing supply transformers by requiring only simple gate/cathode outputs. Available in 110V, 230V, 415V and 480V supply versions, this model is configured for 230V AC operation and includes opto-isolated control inputs, adjustable ramp control, over-current protection, LED status indicators and an RJ45 communications port.
