Silicon-controlled rectifier (SCR) triggering boards are a type of phase-shifting power controller that adjusts the voltage, current, and power of electrical equipment by altering the conduction angle of SCRs. The core component utilizes high-performance, high-reliability SCR triggering dedicated integrated circuits produced abroad.

Main Application Fields: Salt bath furnaces, power frequency induction furnaces, quenching furnace temperature control; heat treatment furnace temperature control; glass production process temperature control; diamond press heating; high-power magnetization/demagnetization equipment; semiconductor industry boat evaporation sources; aviation power supply voltage regulation; vacuum magnetron sputtering power supply; textile machinery; crystal stone production; powder metallurgy machinery; tunnel kiln distributed temperature control system; color picture tube production equipment; metallurgical machinery and equipment; AC/DC motor drives; petrochemical machinery; smooth, infinite adjustment of voltage, current, power, lighting, and constant voltage, constant current, constant power control fields.

The output trigger pulse features high symmetry and stability, and remains unaffected by environmental temperature changes. No adjustment of pulse symmetry or limit is required during operation. Field debugging is typically achievable without an oscilloscope. The thyristor trigger board is widely applicable for voltage and current regulation in various industrial fields, suitable for resistive loads, inductive loads, primary sides of transformers, and various rectifying devices.
