AC/DC Power Converter Assembly (Ground Based Artillery Mobile Radar)

This AC/DC Power Supply was developed to power a HUM-V mounted radar transmitter and receiver. This system consists of a 19” rack, three (3), hot-swappable, AC/DC converters, each delivering a regulated output of 90A at 42VDC as the main power supplies (Main PS), and two (2) multi-output AC/DC converters, as low voltage power supplies (LVPS). It’s modular design allows for easy assembly and reassembly if necessary.
