SCR - B type silicon controlled trigger board uses ARM and 32-bit performance microcontroller as control to trigger the silicon controlled rectifier to achieve AC voltage regulation and power regulation. The control board adopts ten bit A/D, with high output linearization and low output starting point., Realize stepless regulation of the load.
Widely used in silicon controlled rectifier regulation, voltage regulation on the primary and secondary sides of transformers, welding machines, temperature control, excitation, and other occasions.

Product features:
● Fully digital circuit control, 32-bit ARM chip, high stability.
● Multiple input control modes: DC4~20mA, DC1~5V, DC0~10V, potentiometer
● Wide working voltage, input working line voltage can reach a minimum of 4% of the rated voltage, and its control accuracy is basically unchanged.
● Multi pulse trigger, with strong anti-interference ability.
● High trigger power, which can directly trigger 2000A thyristor
● Thyristor trigger precision 2000, suitable for occasions with high accuracy and high requirements
● Soft start function (the soft start time shall be specified in the order) to reduce the instantaneous impact current of the load when it is powered on, effectively protect the safety of the voltage regulator, and extend the load life
● Each input control terminal and the strong current main circuit are designed with full isolation, and the insulation medium withstand voltage is greater than 2000VAC
● Simple wiring and convenient maintenance
● Fully isolated main circuit and control circuit, safe and reliable
