Regenerative Control and Energy Management Features

The GE DS200GSIAG1A DS200GSIAG1ABA Common DC Bus Regenerative Board returns braking energy to the power grid. The board uses IGBTs to invert DC bus voltage back to AC line. A fiber optic interface provides high-noise immunity for control signals. Furthermore, the board includes a dynamic braking option for emergency stopping. Consequently, multiple drives share a common DC bus without wasting braking energy as heat.

Installation and Connection Steps

Mount this GE DS200GSIAG1A DS200GSIAG1ABA Common DC Bus Regenerative Board in the main drive cabinet slot. First, connect the DC bus positive and negative cables to the power lugs. After that, attach the AC line input to the regenerative output terminals. Then, connect the fiber optic cables to the main controller interface. Finally, configure the regenerative current limit using the onboard DIP switches.

Energy Discharge and Safety Notice

This GE DS200GSIAG1A DS200GSIAG1ABA Common DC Bus Regenerative Board stores significant energy in its capacitors. Therefore, you must wait at least five minutes after power removal. The six DC link capacitors discharge through internal bleeder resistors. Never touch the power terminals immediately after system shutdown.

Status Indication and Diagnostics

A green LED indicates the board has DC bus power and operates normally. A yellow LED flashes during active regenerative energy return cycles. A red LED illuminates when the board detects a fault condition. Two additional LEDs show fiber optic link status for each channel.
