It incorporates preassembled and tested front ends (M-FIAM5B or M-FIAM9), Vicor Maxi, Mini and Micro Family DC-DC converters (H or M-Grade), and a choice of output connections and mechanical platforms. The 28 Vdc VIPAC can be specified with one, two or three outputs with voltages as low as 3.3 Vdc to as high as 48 Vdc and power levels from 50 to 400 W per output. Additionally, the wide trim range of the modules can provide operating voltages from 500 mV to 52.8 V. The MIL-VIPAC is available with an input of 28 Vdc in a variety of packages with profiles as low as 0.75".
