The CUI Inc. PCM-400-12-U is an AC/DC power supply from the PCM-400 series, designed for various ITE, telecommunications, and industrial applications. It provides a continuous power output of up to 400W with forced air cooling, or 220W with convection cooling, and features a nominal output voltage of 12Vdc.
Key electrical specifications include a universal input voltage range of 90-264 Vac, active power factor correction (PFC), and an efficiency rating of up to 85%. The unit offers protection against over-voltage, short-circuit, over-current, and over-temperature conditions. It also includes built-in remote ON/OFF control and power good signals.
Mechanically, this power supply is housed in a U-frame package measuring 152.4 x 101.6 x 38.1 mm, suitable for chassis mounting. It operates within a temperature range of 0°C to 50°C at full load, derating to 50% load at 70°C. The PCM-400-12-U meets EN60950-1 standards and carries UL/cUL and TUV safety certifications, along with EN55022 Class B EMI compliance.
The input voltage range is 90 to 264 Vac at 47 to 63 Hz.
