DESCRIPTION

MicroVerter modules are high density DC-

DC converters designed for use in tele-

com and other centralized modular and

distributed power applications. Three

input voltage ranges are available and

all use metal PC boards, planar transformers,

and surface mount construction to pro-

duce up to 252 watts in a tiny package.
