Professional diagnostic and board-level repair service for this Laser Drive, Inc 4001-01-0076/78006 Power Supply.

Laser Drive Inc 4001‑01‑0076/78006 is a high‑power laser diode driver power supply designed for industrial and scientific laser systems, typically operating from 208–230 V AC at up to 20 A. Common failure modes include loss of output voltage due to failed rectifier or regulator components, overheating of the internal heat sink, and degradation of the power MOSFETs under sustained high current loads. First‑check diagnostics: verify incoming mains voltage and continuity of the input fuse; test the output DC rail with a multimeter for correct voltage and ripple; inspect the board for burn marks or swollen electrolytic capacitors and confirm that the heat sink is properly seated and thermally conductive.
