IEC61000-4: Electromagnetic Compatibility, Testing and Measurement Techniques.

IEC 65: Safety of electronic and related equipment for household and similar general use, powered by grid power.

Utilizing industrial-grade high-performance microprocessors, it integrates three regulation methods: open-loop voltage regulation, closed-loop constant voltage, and constant current regulation. It controls silicon-controlled rectifiers to achieve constant voltage limiting current or constant current limiting voltage. Function parameters are set through button operation, with fault alarms and interface parameters displayed on an LED digital tube, and set parameters automatically stored. The control panel features automatic power frequency identification, soft start-up on power-on, gentle shutdown, constant current output, constant voltage output, over-voltage protection, over-current protection, and working status indication. It has single-phase full-bridge rectification and AC triggering capabilities, capable of triggering silicon-controlled rectifiers up to 1000A. Suitable for various load types such as resistive loads, inductive loads, capacitive loads, transformer primary sides, and more in various industrial fields. Widely used in equipment such as electroplating, charging and discharging, single-phase thyristor power supplies, electric heating temperature control, and others.
