The KDGK-II is a comprehensive power test bench designed for high/low voltage switchgear factory testing. It integrates fully-controlled three-phase rectification modules, phase-shift trigger circuits, and automatic regulation circuits to deliver adjustable AC/DC power outputs. The system provides 0~380V three-phase AC, 0~10A AC current, 0~260V DC operating voltage, and fixed voltage outputs (100V AC, 24V/36V/110V/220V DC, 380V/220V AC). With phase-sequence-free input, 2500V isolation, and compatibility with resistive/inductive loads, it offers a safe, flexible solution for switchgear power-on testing.
