The CUI Inc. PSF-155-D-CF is an enclosed AC-DC power supply designed for ITE (Commercial) applications. It delivers up to 155W of continuous power with a universal input voltage range of 90 to 264 VAC and a frequency of 47 to 63 Hz.
This model features three output voltages: two at 27.6 Vdc and one at 5 Vdc. The primary outputs (27.6 Vdc) have a maximum current rating of 3.1 A and 1.73 A respectively, while the tertiary 5 Vdc output has a maximum current of 3 A. The power supply offers an efficiency of up to 85% and includes built-in constant current limit circuitry.
Designed for chassis mounting, the PSF-155-D-CF has dimensions of 129.5mm x 97.5mm x 37.5mm. It operates within a temperature range of -20°C to 70°C with derating. Protections include over-voltage, over-current, short-circuit, overload, brown-out, battery low, and battery polarity protection. It also provides alarm signals for AC OK and battery low.
Safety and compliance approvals include CE, cURus, and TUV. The isolation voltage is rated at 3000 Vac for input-to-output, 1500 Vac for input-to-ground, and 500 Vac for output-to-ground.
