Operation

The FC36MV generates precise firing pulses for high-power three-phase SCR assemblies, providing accurate control of industrial power systems. Users can select between phase-angle, burst-fire, or combination firing modes to suit the application and load characteristics.

The controller accepts analogue voltage, current, and opto-isolated digital control signals while automatically correcting phase rotation and monitoring for phase loss to maintain reliable operation. An adjustable soft-start ramp minimises electrical stress during power-up, while integrated current limiting and over-current protection help safeguard both the firing board and connected power devices.

Selectable load configuration allows the controller to operate efficiently with both resistive and inductive loads, making it suitable for a wide variety of industrial power control systems.
