MIL-COTS PRM™ Regulator and VTM™ Current Multiplier

Rugged factorized power solutions

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 500W, the PRMs produce a nominal factorized bus voltage, controllable over the range of 20 – 55VDC. 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 80A at any output voltage from 1 to 50VDC in a surface-mount package occupying only 1in2.
