MagneTek 3577-16-100 Power Supply Board

MagneTek 3577‑16‑100 is a 100 V DC power‑supply board used in industrial motor drives and servo controllers. Common failure points on this class of boards include overheating of the main switching MOSFETs, degradation of the input/output capacitors, and failure of the voltage regulator ICs or protection diodes. First‑check diagnostics: verify the input AC voltage and filter capacitor condition; measure the output DC rail for correct voltage under load; inspect for burn marks, cracked solder joints, or swollen electrolytics on the board.[oss-gpt-20b]
