GE Fanuc IC695PSA040D RX31 40w power supply

The IC695PSA040D is a 40‑W power supply used in GE Fanuc RX3i backplanes, accepting 85–264 VAC or 100–300 VDC and providing +5.1 VDC, +24 VDC relay output and internal +3.3 VDC rails. Common failures include capacitor degradation causing voltage droop, blown internal fuses, overheating of the heat‑sink or power MOSFETs, and failure of the AC/DC rectifier bridge. First‑check diagnostics are: verify that the input supply is within spec; measure all output voltages with a multimeter to confirm correct rail levels; visually inspect for burnt components, swollen caps, or loose connections before proceeding to component replacement.[oss-gpt-20b]
