Todd Engineering Sales TS-30 Switching Power Supply Repair Service

Professional diagnostic and board-level repair service for this Todd Engineering Sales TS-30 Switching Power Supply.

The Todd Engineering TS‑30 is an automatic transfer power switch rated at 120 V/30 A used to alternate between two AC sources in industrial or motor‑coach applications. Common failure modes include tripped or burned fuses, failed contactors or relay contacts, and degraded input voltage sensing circuits that can cause false switching or no transfer. First‑check diagnostics: verify both input voltages with a multimeter, inspect the main fuse and any circuit breakers for continuity, and visually examine the relay contacts and wiring harness for signs of arcing or corrosion. If the unit still does not switch, review the status LEDs or diagnostic codes (if available) to isolate whether the issue is in the control logic or power path. Post Comment
