Project Description
The MIL-COTS VI BRICK PRM operates from a wide input range of 16 – 50 Vdc, meeting many of the ground vehicle and airborne requirements of MIL-STD-1275 and MIL-STD-704. Rated for 120 W, the 28 V PRM produces a nominal factorized bus voltage of 36 Vdc, controllable over the range of 26 – 50 Vdc. The downstream isolated VI BRICK VTM is available with twelve voltage division ratios from 1:1 to 1:32 and provides the user with flexibility to supply up to 100 A or 120 W at any output voltage from 1 to 50 Vdc in a surface-mount package occupying only 1 square inch.
The MIL-COTS VI BRICK Bus Converter Module (BCM) is a high efficiency (>96%), Sine Amplitude Converter (SAC) operating from MIL-STD-704E/F 270 Vdc and delivering an isolated 30.0 – 41.3 Vdc. The BCM is suitable for use with the MIL-COTS PRM–Regulator and VTM–Current Multiplier, and is ideal for aircraft distributed power applications.
