Grade Operating Storage L = 675W VI = Non RoHS Compliant E = 10 to +85 40 to +100 VE = RoHS Compliant A single high-boost HAM may be used with C = 25 to +85 40 to +100 I = 40 to +85 55 to +100 any combination of V375 series DC-DC M = 55 to +85 65 to +100 converters which are available in Micro, Product Type Mini and Maxi packages with up to 600 HAM = Harmonic Attenuator Module Watts of output power. Versions without HAMD = Harmonic Attenuator Module Driver internal diode bridges (HAMD and BAMD) BAMD = Harmonic Attenuator Module Booster can be operated in parallel to provide power (HAMD and BAMD can be used in parallel expansion capability. The combination of or in arrays for applications that require more the high-boost HAM with V375 DC-DC power than that available from a single HAM) converters results in a power conversion system with twice the power density, fewer components and lower cost compared to previous HAM-based solutions. In addition, the high-boost HAM is fully compatible with Vicor VI-26x and VI-J6x series DC-DC converters. This gives designers the freedom to choose from the industrys broadest selection of DC-DC converters with outputs from 2 to 95V , 50 600 Watts. DC The user need only provide external hold-up capacitors, a few discrete components, and a line filter (available from Vicor).
