Mean Well 547-1-PS Power Supply

Mean Well 547‑1‑PS is a 15 W single‑output switching power supply commonly used to feed low‑power industrial controllers, sensor modules, and small motor drives. Common failure modes for this model include overheating of the internal MOSFETs or inductor windings, degradation of the output filter capacitors, and failure of the protection IC due to overvoltage or short‑circuit events. First‑check diagnostics: verify that the input AC voltage is within spec and that the output DC rail matches the 12 V/1 A rating; inspect the board for burn marks or swollen electrolytics, and test the output with a multimeter while monitoring temperature of the MOSFETs and inductor.[oss-gpt-20b]
