描述

CENB1020A4803F01 is a universal 20 Watt series ITE switch-mode power supply designed for industrial and commercial applications. It features a 48V single output with a maximum current of 0.40A and maximum power of 19.2W, with output ripple and noise of 480mV peak-to-peak maximum at 20MHz bandwidth. The unit accepts 100-240VAC universal input (±10%, 47-63 Hz) with inrush current limiting to 60A peak, and incorporates a fixed-frequency flyback topology with hiccup mode protection for overload and short-circuit conditions. Operating over a temperature range of 0°C to 40°C with no derating, the supply delivers ±1% line regulation and ±5% load regulation, making it suitable for telecommunications, industrial control systems, and embedded applications requiring reliable regulated DC power.
