AC - DC POWER SUPPLY

Dual Input
DC to DC CONVERTER
Output 28V - 150A


The model TRU28-150-DI is a unique high power system designed to accept either 24 VDC input (22-30V) or 3 Phase 4 wire 230/400V 50/60 Hz and produce highly regulated and protected 28V output to 150A. The rugged construction of this unit makes it suitable for the type of shock and vibration encountered in vehicular application. The unit is intended for 19" rack mounting, and interconnects with the input power source and load 64 circular connectors. The unit is intended primarily for high power RF and Microwave transceivers.
