The Mitsubishi FX2N-20PSU is a robust power supply unit that performs reliably in demanding environments. The unit is well-suited for diverse operational scenarios with its input voltage range stretching from 85V to 264V AC. It supports a standard operating voltage of 100 to 240V AC at 50 or 60 Hz, adapting well to various electrical systems.

In terms of output specifications, this power supply delivers a voltage of 24V DC, adjustable within ±10%. Users can expect a maximum output current of 2A, with a minimum requirement of 0.2A when temperatures exceed 40°C. The unit's design minimizes ripple noise, ensuring that it remains below 500 mVp-p.

The FX2N-20PSU features comprehensive safety measures, including overcurrent protection that automatically activates between 110% and 160% of the rated capacity. Similarly, overvoltage protection kicks in at levels between 110% and 140%, employing diode clamping without the benefit of auto recovery. This unit can handle inrush currents up to 60A at 200V AC.

Operating temperature capabilities range from 0°C to 55°C, and the unit can be stored in conditions with temperatures between -20°C and 70°C. An indicator LED shows green when voltage output is active, offering clear operational feedback. The fuse rating is a time-lag fuse rated at 250V, 3.15A, ensuring effective protection against overloads.
