Astrodyne Corporation 35 Hampden Road Tel: (508) 964-6300 Fx: (508) 339-0375 nV300LF 82.5-120 Watts 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.
