PSF-155-D-CNF

This CUI Inc. PSF-155-D-CNF is an enclosed AC/DC power supply designed for commercial ITE applications. It delivers a total continuous power of 155W and features a universal input voltage range of 90-264 VAC.

The converter provides three distinct output voltages: two at 27.6 Vdc (Vo1 and Vo2) and one at 5 Vdc (Vo3). The primary outputs (Vo1) can deliver up to 5.1A, the secondary outputs (Vo2) up to 2.1A, and the tertiary output (Vo3) up to 3A. It includes built-in constant current limit circuitry and offers protections against short circuit, overload, over voltage, brown-out, battery low, and battery polarity.

With a compact chassis mount design measuring 179.0mm x 98.0mm x 38.0mm, this power supply is suitable for integration into various systems. It operates within a temperature range of -20°C to 70°C with derating and boasts an efficiency of up to 85%. Safety approvals include CE, cURus, and TUV.

Key electrical specifications include line and load regulation of ±0.5% for Vo1 and ±1.5% for Vo3, voltage accuracy of ±2% for Vo1 and ±3% for Vo3, and a hold-up time of 30ms. It also features an AC OK signal and battery low signal, with the AC OK signal being a relay contact output for this specific model (PSF-155-D-CNF).
