VPTHVM-270 Bus Converter
With up to 200W of output power, this regulated bus converter module operates from a 270V bus to step down the power to create a 28V bus for your power system. A wide input voltage range accommodates MIL-STD-704 input power requirements for avionics, mobile, ground and other applications. The high efficiency design reduces input power requirements and eases thermal management.
