Laser Drive 4001-01-0076 High volt power supply Repair Service

Professional diagnostic and board-level repair service for this Laser Drive 4001-01-0076 High volt power supply.

Laser Drive 4001‑01‑0076 is a high‑voltage power supply unit (HVPS) used in Candela Mini GentleLASE MGL laser systems and similar industrial laser drivers. Common failures include degraded output due to aging capacitors, insulation breakdown of the HV transformer, or failure of the internal MOSFET array; these often manifest as voltage sag, overheating, or erratic shut‑down. First‑check diagnostics: verify input AC supply and measure DC bus voltage for correct regulation, inspect all electrolytic caps for bulging/leakage and test the MOSFETs for continuity and drain‑source leakage, then review any error codes from the laser controller for indications of HV over‑voltage or protection trips.
