Introduction

The VI Brick® AC Front End Evaluation Board oers a convenient means to evaluate
the performance of Vicor’s VI Brick AC Front End module and has been optimized for
user convenience. Refer to the table below for operating conditions and limits.

This product contains an input line filter. It is important to remember the response
of the AC line filter is dependent upon the wiring connected to the evaluation board.
Care should be exercised to minimize stray source impedances in order to fully
exercise the features of the converter.
