300 VDC Input
1/2 Brick
NanoVerter Series
The nV300LF NanoVerter modules are high density DC-DC
converters with an input range of 220-400 VDC. These supplies
utilize metal PC boards, planar transformers, and surface mount
construction to produce up to 120 watts in a small package with
maximium reliability. The converters are board mountable with
isolation of 4500 VDC (input to output), are fully encapsulated
with base-plate cooled operation up to 100°C and have been
qualified to international safety standards including the latest
Lead-Free and RoHS requirements. These converters are ideal
for customers who need reliable power conversion in a compact,
conduction cooled package.
