Cherokee International Inc. MP401C1 4A Power Supply
 |
The Cherokee MP401C1 4A is a 444 W, 100‑240 VAC input, 50/60 Hz output power supply used in industrial automation and PLC systems. Common failure points include the main rectifier bridge, smoothing capacitors, and the switching MOSFETs or IGBT stages that can burn out under overvoltage or overheating; a failed output regulator IC will also cause intermittent dropout. First‑check diagnostics: verify input voltage and polarity with a multimeter, confirm output rails (24 VDC/48 VDC) are within spec, inspect for obvious signs of capacitor bulging or thermal damage, and check the status LEDs or fault codes on the unit’s diagnostic port if available.[oss-gpt-20b] |
