Jay Electronique PWCB020S1307 Charger

Jay Electronique PWCB020S1307 is a 9 VDC battery charger rated at 500 mA, powered from 230 VAC input. Common failure points include the AC‑to‑DC rectifier/bridge, smoothing capacitor degradation, and the internal MOSFET or linear regulator that limits output current; these components often fail due to thermal cycling or overvoltage. First‑check diagnostics: verify 230 VAC supply voltage and polarity at the charger inlet, measure the DC output under load for correct voltage and current compliance, and inspect the board for burnt traces, cracked solder joints, or swollen electrolytic capacitors. If these pass, perform a continuity test on the rectifier bridge and check the MOSFET gate drive circuitry for proper biasing.[oss-gpt-20b]
