Todd Engineering Sales PC 75 power supply Repair Service

Professional diagnostic and board-level repair service for this Todd Engineering Sales PC 75 power supply.

Todd Engineering PC75B is a 75‑amp, 12 VDC industrial power supply used as a battery charger or high‑current DC source in heavy‑equipment and automotive applications. Common failure points include blown input fuses, degraded output capacitors causing voltage ripple, overheating of the regulator section, and internal shorted MOSFETs that can damage the board. First‑check steps: verify 110 VAC (or specified line) input voltage and ensure the main fuse is intact; measure the regulated 12 VDC output for continuity and ripple using an oscilloscope; visually inspect the PCB for burnt components, cracked solder joints, or swollen electrolytics before proceeding with component replacement.
