Interface parameters and fault warnings are displayed via an LED digital tube menu, and settings are automatically saved.
Features:The ST30 three-phase rectifier thyristor voltage regulator module utilizes a high-performance industrial-grade 32-bit microprocessor and is designed with high digital safety standards. It supports remote network control and local control modes, fuzzy-PID parameter adjustment, open-loop voltage regulation, closed-loop constant voltage, and constant current control. The three adjustment modes are integrated, allowing the thyristor to control constant voltage with current limiting or constant current with voltage limiting. Interface parameters and fault warnings are displayed via an LED digital tube menu, and settings are automatically saved. The control board includes functions such as phase loss protection, soft start on power-up, soft shutdown, constant current output, constant voltage output, overvoltage protection, overcurrent protection, short-circuit protection, and working status alarms. It has a fully controlled three-phase bridge rectifier and anti-parallel AC thyristor trigger mode, capable of triggering thyristors under 1000A, suitable for resistive loads, inductive loads, capacitive loads, and primary transformer loads for voltage and current regulation in various industrial applications. It is widely used in electroplating, battery charging and discharging, three-phase thyristor power supply, electric heating temperature control, arc discharge control, and other equipment.
