MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200GSIAG1C DS200GSIAG1CHD Common DC Bus Regenerative Board returns braking energy from multiple drives to the AC supply. This board connects several drive inverters to a shared DC bus configuration. You will find it recovering energy during motor deceleration or overhauling load conditions. It substantially reduces total system power consumption and cabinet heat dissipation.
Core Technical Specifications
The GE DS200GSIAG1C DS200GSIAG1CHD 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 all power component heights. The total assembly weighs approximately 1.4 kilograms. Six IGBT modules handle the bidirectional regenerative power conversion process. Three AC line reactors filter the returning current waveform before it reaches the grid.

Connectors and Bus Bar Interfaces
The GE DS200GSIAG1C DS200GSIAG1CHD Common DC Bus Regenerative Board uses heavy-duty screw terminals for all power connections. Two copper bus bars connect the board to the common DC bus positive and negative rails. Three AC line terminals connect directly to external line reactors and protective contactors. A 20-pin header carries gate drive timing signals from the main system controller. Additionally, the board includes fiber optic ports for electrically isolated communication.
Protection and Monitoring Features
This regenerative board includes fast-acting overcurrent protection on all three AC phases. The board also monitors DC bus voltage continuously for overvoltage conditions. Moreover, the GE DS200GSIAG1C DS200GSIAG1CHD Common DC Bus Regenerative Board integrates IGBT temperature sensing on every power module. A red LED illuminates immediately during any fault condition or overtemperature event. The board automatically disables regeneration when a fault occurs to prevent damage.
Energy Storage and Thermal Management
This board contains large DC link electrolytic capacitors on the input power stage. These capacitors store approximately 50 joules of energy at nominal operating voltage. Therefore, the board retains hazardous energy for several minutes after disconnection. The GE DS200GSIAG1C DS200GSIAG1CHD Common DC Bus Regenerative Board requires forced-air cooling with minimum 300 LFM airflow. Wait 10 minutes after power removal before touching any terminal or bus bar. Do not operate the board without proper AC line reactors installed.
