ABB DDC779CE102 3BHE027859R0102 Distributed Digital Control Board

Product Description

DDC779CE102 (Order No.: 3BHE027859R0102) is an ABB DDC distributed digital control board for power cells of ACS5000 and ACS6000 medium voltage IGCT high-power drives. It is the main control board for DTC Direct Torque Control. It performs high-speed sampling of DC-link voltage, current and IGCT junction temperature, executes control algorithm and outputs firing signals. Equipped with fiber optic communication ports for galvanic isolation between high voltage and control side. It supports fault recording and closed-loop speed regulation. The PCB is coated with conformal coating and clip-mounted inside power cell. It is original spare part for drive maintenance, obsolete by manufacturer, only available as stock spare for legacy medium voltage drive replacement.
