The CUI Inc. PSF-155-A-CF is an enclosed AC-DC power supply with a continuous power output of up to 155W. It features a universal input voltage range of 90-264 Vac and provides dual 13.8 Vdc outputs.
This model offers high efficiency up to 86% and includes built-in protections such as short circuit, over load, and over voltage. It also features an alarm signal for AC OK and battery low conditions, along with brown-out, battery low, and battery polarity protections.
The power supply is designed for chassis mounting and 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 and meets safety approvals including CE, cURus, and TUV.
Key electrical specifications include line regulation of ±0.5%, load regulation of ±0.5% for Vo1 and ±1.5% for Vo3, and voltage accuracy of ±2% for Vo1 and ±3% for Vo3. The unit also provides a hold-up time of 30 ms at full load.
The converter provides two 13.8V outputs with a total power of 155W.
The input voltage range is 90-264 Vac.
The operating temperature range is -20°C to 70°C with derating.
Typical efficiency is 86% at full load.
Over-voltage protection (115-150% latch-off) and over-current protection (110% hiccup mode) are included.
The converter is enclosed in a chassis mount package measuring 129.5mm x 97.5mm x 37.5mm.
Input-to-output isolation is 3000 Vac.
