The TSCR-B and NG3A-C three-phase thyristor trigger boards use ARM, a 32-bit performance microcontroller as the control to trigger the thyristor to achieve AC voltage 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, electroplating, water treatment, 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. Excellent three-phase balance performance
● High trigger power, which can directly trigger 2000A thyristor
NG3C-A thyristor trigger precision 2000, suitable for high-precision and demanding occasions, with adjustable soft start time
● 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
● The design is novel and unique, without the need for external synchronous transformers and without phase sequence restrictions
● Fully isolated main circuit and control circuit, safe and reliable
