The PowerSpec HOAU242004 (part 6693006602) is a 24‑V/20‑A industrial power supply board used to feed control panels, servo drives or motor controllers in factory automation systems. Common failures on this model include burned capacitors, cracked PCB traces, and overheating due to overcurrent or poor ventilation; the integrated switching regulator can also fail if input voltage exceeds its limits. First‑check diagnostics: verify that the unit receives the correct input voltage (48–60 V DC) and measure output rails for 24 V ±5%; inspect for visible damage such as bulging electrolytics or scorch marks; finally, review any diagnostic LEDs or error codes on the host controller to confirm whether the supply is being cycled or tripped.[oss-gpt-20b]
