The Arestech AEP001‑24 is an industrial switch‑mode power supply designed to deliver regulated DC output for control panels and servo drives. Common failure modes on this model include capacitor degradation leading to ripple or dropout, transformer winding insulation breakdown, and regulator IC overheating due to overcurrent or poor ventilation. First‑check diagnostics: verify input AC voltage and polarity, measure output rails (typically 5 V, 12 V, 24 V) with a multimeter for correct levels and ripple; inspect the board for bulging or leaking electrolytics and scorch marks; and review any diagnostic LEDs or error codes that may indicate shorted outputs or protection trips.[oss-gpt-20b]
