Professional diagnostic and board-level repair service for this Efratom MPS-AC 105450-001 Power Supply.

Efratom MPS‑AC 105450‑001 is a modular AC power supply used in timing and frequency distribution systems, delivering 115/230 V to front‑ and rear‑backplanes of MFTS/MFTD platforms. Common failure points on this model include degraded capacitors or electrolytic failures on the input/output filtering stages, shorted rectifier diodes, and overheating of the internal switching regulator due to dust or thermal cycling. First‑check diagnostics: verify incoming AC voltage and polarity; measure output rails with a calibrated multimeter for correct voltage and ripple; inspect the board for bulging capacitors, burnt components, or solder joint cracks; review any error logs or status LEDs that may indicate over‑temperature or protection shutdowns.
