This CUI Inc. PSF-155-C-CF is a versatile AC/DC power supply designed for commercial ITE applications. It provides a total output power of 155W, with three distinct voltage outputs: 27.6 Vdc, 27.6 Vdc, and 5 Vdc. The unit operates with a universal input voltage range of 90 to 264 VAC, making it suitable for global use.
Key electrical specifications include a typical efficiency of 85%, line regulation of ±0.5%, and load regulation of ±0.5% for the primary outputs. It offers protections such as over-voltage, over-current, and short circuit.
The converter is housed in an enclosed chassis mount package, measuring 129.5mm x 97.5mm x 37.5mm. It operates within a temperature range of -20°C to 70°C with derating. Safety approvals include CE, cURus, and TUV.
Features like built-in constant current limit circuitry, alarm signals for AC OK and battery low, and resistance to 2G vibration make it a robust solution for various industrial and commercial applications.
