The Power Source PC‑30 is a 12 VDC battery charger supply rated for 30 A output from a 100–130 V AC input (≈415 W). Known failure modes in this class include degraded electrolytic capacitors on the rectifier/filter stage, transformer winding insulation breakdown, and overheating of the internal power MOSFETs or heatsinks. First‑check diagnostics: verify the AC mains voltage and polarity at the inlet; measure the 12 V output under no load and with a typical 30 A load to confirm regulation; visually inspect for bulging capacitors, burnt components, or excessive heat on the heat sink and MOSFETs.[oss-gpt-20b] |
