MI-200 Features TM Military DC-DC Converters 50 to 100W Inputs: 28Vdc per MIL-STD-704D/E 155Vdc per MIL-STD-1399A 270Vdc per MIL-STD-704D/E Single output: 2 – 48Vdc Up to 23W/in3 MIL-STD-810 environments Current limit OVP and thermal shutdown Power boosters for higher power outputs ZVS/ZCS power architecture Low noise FM control Size: 4.6" x 2.4" x 0.5" (116,8 x 61,0 x 12,7mm) Product Highlights The MI-Series is designed for military applications and is based on Vicor’s 1st Generation family of zero-current/zero-voltage switching, component level DC-DC converters. Operating at frequencies in excess of 1MHz, the MI-Series offers state-of-the-art performance in terms of power density, efficiency, noise, ease of use, and reliability. All units are manufactured in ISO 9001-registered facilities. Full epoxy encapsulation in Vicor’s industry standard package enables the MI-Series to meet MIL-STD-810 environmental requirements for humidity, fungus, salt, fog, explosive atmosphere, acceleration, vibration, and shock. (See page 32.) Standard features such as wide output trimming/programming, current limiting, remote sense, output inhibit, and latching OVP and OTP combine to offer a high degree of protection, versatility, and reliability for military power systems.
