Mean Well 547-1A-PS Power Supply

Mean Well 547‑1A‑PS is an industrial AC‑to‑DC switching power supply rated at 1 kW, commonly used to feed motor drives, PLCs, and other control equipment in automation systems. Typical failure modes for this class include capacitor degradation (especially electrolytic on the input side), overheating of the internal MOSFET or transformer due to overcurrent or poor ventilation, and output voltage sag under load. First‑check diagnostics: verify that the unit receives proper 120/240 VAC input and measure the output DC rail; inspect for visible signs of component burn or bulging capacitors; and review any error LEDs or diagnostic outputs from the host controller for clues to a protection trip.[oss-gpt-20b]
