Laser Drive Inc. 4001-01-0078/8009 Rev H Power Supply Repair Service

Professional diagnostic and board-level repair service for this Laser Drive Inc. 4001-01-0078/8009 Rev H Power Supply.

Laser Drive Inc. 4001‑01‑0078/8009 Rev H is a high‑voltage power supply module used in industrial laser drive systems to provide the regulated DC and HV outputs required for beam generation. Common failure modes on this board include degraded electrolytic capacitors (especially the HV filter caps), over‑stress of the voltage regulator ICs, and shorted or damaged output diodes that cause loss of high‑voltage output or erratic regulation. Initial checks should verify input supply integrity (48 V/AC conversion), inspect for visible burn marks or swollen caps on the main power section, and measure the HV output with a proper isolation meter to confirm correct voltage levels before proceeding to component‑level diagnostics.
