Mitsubishi Electric Corporation FM400TU-2A Power Supply

The Mitsubishi FM400TU-2A is a DIN-rail or panel-mount DC power supply module that delivers regulated 24 VDC to Mitsubishi PLCs, I/O modules, and field devices in automation systems. It accepts standard industrial AC input of 100–240 VAC and provides approximately 2 A of output current (platform dependent), with screw-terminal field connections for secure wiring. Designed for control cabinets and machine panels, it operates in an industrial temperature range and includes overload and short-circuit protection plus Power ON and fault status LEDs to simplify diagnostics in factory environments such as conveyors, packaging machinery, material handling, and assembly lines. Common replacements in Mitsubishi ecosystems include Mitsubishi S8VK-G24024 and Mean Well NES-150-24 switching power supplies.
