PRM-VTM-MILCOTS.jpg

Description

The MIL-COTS PRMs meet many of the ground vehicle and airborne requirements of MIL-STD-1275 and MIL-STD-704. Rated for up to 500 W, the PRMs produce a nominal factorized bus voltage, controllable over the range of 26 – 50 VDC or 20 – 55 VDC. The downstream isolated VTM is available with twelve voltage division ratios from 1:1 to 1:32 and provides the user with flexibility to supply up to 80 A at any output voltage from 1 to 50 VDC in a surface-mount package occupying only 1 in2.
