MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200GSIAG1C DS200GSIAG1CFD Common DC Bus Regenerative Board returns braking energy to the AC line. This board connects multiple drives to a shared DC bus configuration. You will find it recovering energy during motor deceleration or overhauling loads. It significantly reduces overall system power consumption and heat dissipation.
Core Technical Specifications
The GE DS200GSIAG1C DS200GSIAG1CFD Common DC Bus Regenerative Board measures 35.0 cm in width and 27.0 cm in height. Its board depth equals 5.0 cm including power component heights. The total assembly weighs approximately 1.4 kilograms. Six IGBT modules handle the regenerative power conversion process. Three AC line reactors filter the returning current waveform.

Connectors and Bus Bar Interfaces
The GE DS200GSIAG1C DS200GSIAG1CFD Common DC Bus Regenerative Board uses heavy-duty screw terminals for power connections. Two copper bus bars connect the board to the common DC bus positive and negative rails. Three AC line terminals connect to external line reactors and contactors. A 20-pin header carries gate drive signals from the main controller. Additionally, the board includes fiber optic ports for isolated communication.
Protection and Monitoring Features
This regenerative board includes overcurrent protection on all three AC phases. The board also monitors DC bus voltage continuously for overvoltage conditions. Moreover, the GE DS200GSIAG1C DS200GSIAG1CFD Common DC Bus Regenerative Board integrates IGBT temperature sensing on every module. A red LED illuminates during any fault condition or overtemperature event. The board automatically disables regeneration when a fault occurs.
Energy Storage and Thermal Management
This board contains large DC link capacitors on the input stage. These capacitors store approximately 50 joules of energy at nominal voltage. Therefore, the board retains hazardous energy for several minutes after disconnection. The GE DS200GSIAG1C DS200GSIAG1CFD Common DC Bus Regenerative Board requires forced-air cooling with minimum 300 LFM airflow. Wait 10 minutes after power removal before touching any terminal. Do not operate the board without proper AC line reactors installed.
