Maris GS-20/800 DC Power Supply Repair Service

Professional diagnostic and board-level repair service for this Maris GS-20/800 DC Power Supply.

Maris GS‑20/800 is a compact 2 kW DC power supply rated at 800 V with automatic arc‑suppression and high‑current output (≈5 A). Common failures include fuse blow or relay trip due to over‑current, regulator or voltage‑reference drift leading to output voltage sag, and internal capacitor degradation causing ripple spikes. First‑check steps: verify input mains voltage and polarity, test the main fuse and any auxiliary fuses for continuity, then measure the DC output with a calibrated voltmeter while monitoring for arc‑suppression indicator lights. If the supply still fails, inspect the internal regulator ICs and electrolytic capacitors for bulging or leakage before proceeding to component replacement. Post Comment
