Ratelco 100-3575-25 voltage rectifier

Ratelco 100‑3575‑25 is a high‑efficiency AC‑to‑DC voltage rectifier used in industrial control panels to supply regulated DC power for drives, controllers and monitoring equipment. Common failure modes for this class of rectifiers include diode or bridge failure due to overvoltage/overcurrent, capacitor degradation causing ripple, and heat sink or fan failure leading to thermal shutdown. First‑check diagnostics: verify input AC voltage and polarity; measure output DC voltage under no load and with a representative load; inspect the board for burnt components, cracked solder joints, or loose connections; review any associated error codes from the host controller.[oss-gpt-20b]
