Todd Engineering 3808 Power Supply Repair Service

Professional diagnostic and board-level repair service for this Todd Engineering 3808 Power Supply.

The Todd Engineering 3808 Power Supply is a rugged industrial DC supply used in drive and control systems, typically delivering 12‑48 V at up to 5 A. Common failure modes for this class include overheating of the main switching transformer, degradation of rectifier diodes or capacitors, and failure of the onboard voltage regulator ICs. Begin by verifying input AC voltage and measuring output DC rails; check for excessive heat on the transformer core and inspect electrolytic capacitors for bulging or leakage. Next, examine all fuses and resettable PTC devices, then test the switching MOSFETs and gate driver circuitry for open or shorted conditions. Finally, review any diagnostic LEDs or error codes that may indicate over‑current or thermal shutdown events. Post Comment
