OUTPUT SPECIFICATIONS
For comprehensive data on any of the configurations, please refer to the data sheet for the BCM with output voltage (K Factor) of
the Intermediate Bus Converter of interest. Data sheets are available from our website at www.vicorpower.com.
Electrical characteristics apply over the full operating range of input voltage, output load (resistive) and case temperature,
unless otherwise specified.
Note 1: Current limit parameter does not apply for all models. Please see product matrix on page 2 for exceptions.
Note 2: For important information relative to applications where the unit is subjected to continuous dynamic loading, contact Vicor
