Product Overview
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 VI BRICK PFM converter
consistently delivers high efficiency across worldwide AC mains.
Modular PFM converters and downstream DC-DC VI BRICK products
support secondary-side energy storage and efficient power distribution
at 48 V, providing superior power system performance and con-
nectivity from the wall plug to the point-of-load.
