The TDK FMP05‑R60 is a compact AC‑DC switching power supply providing 5 V at up to 0.6 A (3 W) from 85–132 V AC input, commonly used as an auxiliary or control‑board supply in industrial equipment. Typical failure points for this class include transformer winding insulation breakdown, capacitor degradation on the output filter, and thermal overload of the switching MOSFETs, which can manifest as a loss of output voltage or overheating. First‑check diagnostics: verify the input AC voltage and current draw; measure the 5 V rail under load to confirm regulation; inspect for visible signs of component burn‑in or electrolyte leakage on capacitors; review any error logs from the host controller that reference power‑supply faults.[oss-gpt-20b]
