FC36MV 230V Three-Phase Dual Mode Thyristor Firing Board

The FC36MV Dual Mode Firing Board is a high-performance, microprocessor-based thyristor driver designed for precise control of three-phase power systems in demanding industrial environments. Engineered for seamless integration into power control assemblies, this advanced firing circuit enables efficient and reliable control of SCRs (thyristors) across a wide range of applications.

Supporting both phase-angle and burst-fire control modes—as well as a combination of both—the FC36MV provides exceptional flexibility for managing resistive and inductive loads. Its intelligent design includes auto phase rotation correction and phase-loss detection, eliminating common installation challenges and ensuring stable operation without the need for external phasing transformers.

The unit features opto-isolated analogue and digital inputs, allowing compatibility with multiple control signals including 0–5V, 0–10V, 4–20mA, and 5–24V DC. Additional functionality such as adjustable ramp control (0–30 seconds), current limiting, and overcurrent protection ensures smooth startup and enhanced system safety.

Housed in a DIN rail enclosure, the FC36MV offers a compact, durable, and easy-to-install solution for high-power industrial control systems. Designed for precision, reliability, and flexibility, it is an ideal choice for engineers working with complex three-phase power applications.
