Todd Engineering PC 75 Power Supply Repair Service

Professional diagnostic and board-level repair service for this Todd Engineering PC 75 Power Supply.

Todd Engineering PC‑75 is a 75 A, 12 VDC industrial power supply/battery charger commonly used in RV and automotive applications. Typical failure modes for this class include input/output fuse rupture, overheating of the main switching regulator or MOSFETs, degradation of electrolytic capacitors leading to output ripple, and loss of control IC function due to voltage spikes. Begin troubleshooting by verifying that the 120 VAC/12 VDC input is within spec, checking all fuses and the main power switch for continuity, inspecting the board for burn marks or swollen capacitors, and measuring the regulated 12 V output while monitoring for excessive ripple or dropout under load.
