Ratelco 100-3574-25 voltage rectifier

The Ratelco 100‑3574‑25 is a constant‑voltage rectifier that converts AC to DC (typically 12 VDC at 25 W or 24 V/10 A depending on configuration). Common failure modes include diode bridge breakdown, electrolytic capacitor leakage or bulging, and thermal over‑stress leading to insulation degradation. First‑check steps are: verify input AC voltage and polarity, measure output DC voltage with a multimeter while the unit is powered, inspect for visible signs of overheating (burnt components, cracked housings), and check for any error codes on connected drives or controllers.[oss-gpt-20b]
