Schneider VX5A1HC1622 Inverter Power Board

Feature & Principle

It is the dedicated power board for Schneider Altivar 61 and Altivar 71 high-power inverters. It completes AC rectification, DC link power distribution and IGBT power drive signal transmission. It cooperates with the gate driver board to control the switching of power modules, converts three-phase alternating current into adjustable frequency alternating current to drive motors. Integrated overcurrent, overvoltage and temperature detection circuits provide power stage protection for the whole drive.
