The CUI Inc. PCM-400-18-CF is a high-performance AC-DC power supply designed for ITE (Commercial) applications. It delivers a continuous output power of 400W with a preset output voltage of 18Vdc, adjustable within a range of 16Vdc to 20Vdc. The unit operates with a universal input voltage range of 90-264 Vac and features active power factor correction (PFC) for improved efficiency.
Key electrical specifications include an input current of 8A at 90 Vac full load, and an output current of up to 22.22A with forced air cooling or 12.22A with convection cooling. The power supply offers an efficiency of up to 85% and includes protections against over voltage, short circuit, over current, and over temperature. It also features built-in remote ON/OFF functionality and a power good signal.
