The PSK-30D-48 from CUI Inc. is a high-performance AC-DC converter designed for board-mount power supply applications. It provides a regulated 48 Vdc output at up to 0.63 A, delivering 30.2 W of continuous power. The converter accepts a wide universal input range of 85 to 305 VAC or 120 to 430 VDC, making it suitable for global use. With an efficiency of up to 90% at 230 VAC, it minimizes power loss and heat generation.
This converter includes comprehensive protection features such as over voltage protection (60 Vdc hiccup), over current protection (110% auto recovery), and short circuit protection (continuous, hiccup, auto recovery). It also offers a hold-up time of 10 ms at 115 VAC and 50 ms at 230 VAC, ensuring stable operation during brief input interruptions. The output ripple and noise is limited to 150 mVp-p at full load.
The PSK-30D-48 operates over a wide temperature range of -40°C to 85°C with derating, making it suitable for demanding environments. It complies with safety standards IEC/EN/UL 62368, 61558, and 60335, and meets Class B emissions requirements. The converter measures 69.5 mm x 39.0 mm x 24.0 mm and features a compact, board-mountable package.
