Laser Drive 4001-01-0079/78012 High volt power supply Repair Service

Professional diagnostic and board-level repair service for this Laser Drive 4001-01-0079/78012 High volt power supply.

Laser Drive 4001‑01‑0079/78012 is a high‑voltage power supply module used in industrial laser systems (e.g., Candela Perfecta VBeam 2), delivering up to ~3 kW at 2900 VDC from a 208–230 V AC input. Common failure points for this class include burned or failed MOSFETs/IGBTs, capacitor degradation on the high‑voltage output stage, and overheating of the internal heat sink or fan; secondary issues often involve damaged isolation transformers or control ICs that trigger over‑current protection. Begin diagnostics by verifying the incoming AC voltage and current draw, inspecting the HV output for continuity and leakage, and checking the temperature of the power stage components; also review any fault codes from the laser controller’s diagnostic interface.
