GE DS200SSBAG1B DS200SSBAG1BAA Snubber Board

This GE DS200SSBAG1B DS200SSBAG1BAA Snubber Board protects power semiconductors from voltage transients. The board connects directly across each SCR or thyristor in the bridge circuit. You will find this component in many GE Mark V excitation and drive systems. The DS200SSBAG1BAA variant includes the standard factory configuration without conformal coating.

Transient Suppression and Protection Features

The GE DS200SSBAG1B DS200SSBAG1BAA Snubber Board limits voltage rise across each semiconductor during commutation. Each channel combines a 15 Ω resistor with a 0.33 µF capacitor. This RC network absorbs energy from parasitic inductances in the power circuit. Furthermore, the board prevents false triggering from high dv/dt events. Consequently, your SCR bridge operates reliably even under harsh switching conditions.

Installation and Connection Steps

Mount this GE DS200SSBAG1B DS200SSBAG1BAA Snubber Board near the power bridge in the drive cabinet. First, connect each channel’s terminals across one SCR’s anode and cathode. After that, verify all six connections match the correct phase assignments. Then, secure the board using four M3 mounting screws. Finally, check that no terminals touch adjacent circuits before powering up.

Energy Discharge and Safety Notice

This GE DS200SSBAG1B DS200SSBAG1BAA Snubber Board stores energy in its six capacitors. Therefore, you must wait at least one minute after power removal. The capacitors discharge through their series resistors naturally. Never short the terminals to discharge them faster.

Status Indication and Diagnostics

This snubber board has no active indicators or LEDs. However, you can test each RC network with an LCR meter. A failed capacitor typically shows as a short or open circuit. A burned resistor indicates excessive switching energy in that phase.
