GE DS200GSIAG1A DS200GSIAG1ABA Regenerative Board

The GE DS200GSIAG1A DS200GSIAG1ABA Common DC Bus Regenerative Board recovers braking energy from multiple drive inverters. This board connects several drive modules to a shared DC bus configuration. You will find it returning energy to the AC line during motor deceleration. It significantly reduces overall system power consumption and heat generation.

Core Technical Specifications

The GE DS200GSIAG1A DS200GSIAG1ABA Common DC Bus Regenerative Board measures 34.0 cm in width and 26.0 cm in height. Its board depth equals 5.0 cm including all power component heights. The total assembly weighs approximately 1.3 kilograms. Six IGBT modules handle the bidirectional regenerative power conversion process. Three AC line reactors filter the returning current waveform before grid connection.

Connectors and Bus Bar Interfaces

The GE DS200GSIAG1A DS200GSIAG1ABA 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 protection 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 DS200GSIAG1A DS200GSIAG1ABA 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 system damage.

Energy Storage and Thermal Management

This board contains large DC link electrolytic capacitors on the input power stage. These capacitors store approximately 45 joules of energy at nominal operating voltage. Therefore, the board retains hazardous energy for several minutes after disconnection. The GE DS200GSIAG1A DS200GSIAG1ABA 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.
