Maris GS20 Power Supply Repair Service

Professional diagnostic and board-level repair service for this Maris GS20 Power Supply.

Maris GS20 is a compact DC plasma/industrial power supply designed for high‑current, low‑voltage applications such as ion sources and pulse generators. Common failure points include the input rectifier bridge (often shorted by surge), the internal MOSFET or IGBT array (thermal runaway or latch‑up), and the arc‑suppression circuitry (capacitor discharge paths). The unit also tends to exhibit overheating if cooling fans are obstructed or if the enclosure is sealed. First‑check diagnostics: verify mains voltage and polarity, measure output under load for correct voltage/current, inspect for burnt components or swollen electrolytics, and review any error LEDs or serial status codes that may indicate regulator or protection trip conditions.
