Delta Electronics DPSN-465AB power supply

Delta Electronics DPSN‑465AB is a 465 W, 100‑240 V AC / 48‑63 Hz open‑frame power supply commonly used in Cisco Catalyst switches and other industrial equipment. Common failure points include the primary rectifier bridge, output filter capacitors, and the internal fan or heatsink if overheating occurs. First‑check diagnostics: verify input voltage and polarity on the AC terminals; measure output DC rails (48 V, 12 V, etc.) with a multimeter for correct voltage and ripple; inspect for bulging or leaking electrolytic capacitors and ensure the cooling fan is operating.[oss-gpt-20b]
