CPS-10FB DC Power Supply

The CPS-10FB is a high-reliability multi-output DC power supply, originally designed by Fuji Electric for CNC and industrial control systems. It provides stable +5 V, ±12 V, and +24 V DC outputs from a single AC input, delivering 400 VA rated capacity with built-in overvoltage, overcurrent, and short-circuit protection. Compact and rugged, it ensures consistent power for control boards, I/O modules, and servo peripherals in automation environments.
