Izolovaný AC-DC konvertor s funkcí PFC



Product Features

Product Description

The VI Brick PFM Isolated AC-DC Converter with PFC is an AC-to-DC converter, operating from a rectified universal AC input to generate an isolated 48 Vdc output bus with power factor correction. With its ZVS high frequency Adaptive Cell™ topology, the ultra thin PFM converter consistently delivers high efficiency across worldwide AC mains. Modular PFM converters and downstream DC-DC VI Chip products support secondary-side energy storage and efficient power distribution at 48 V, providing superior power system performance and connectivity from the wall plug to the point-of-load.
