GE DS200IPCSG1A DS200IPCSG1ABC IGBT Snubber Card

This GE DS200IPCSG1A DS200IPCSG1ABC IGBT Snubber Card protects IGBT modules from voltage transients during switching. The card connects directly across each IGBT in the power inverter bridge. You will find this component in many GE drive and excitation systems. The DS200IPCSG1ABC variant includes the standard factory configuration without coating.

Transient Suppression and Protection Features

The GE DS200IPCSG1A DS200IPCSG1ABC IGBT Snubber Card limits voltage spikes across each IGBT during turn-off. Each channel combines a 10 Ω resistor with a 0.22 µF capacitor. This RC network absorbs energy from parasitic inductances in the DC bus. Furthermore, the card includes a fast recovery diode in series with each resistor. Consequently, your IGBT modules operate safely under harsh switching conditions.

Installation and Connection Steps

Mount this GE DS200IPCSG1A DS200IPCSG1ABC IGBT Snubber Card near the IGBT bridge in the drive cabinet. First, connect each channel’s terminals across one IGBT’s collector and emitter. After that, verify all six connections match the correct phase assignments. Then, secure the card using four M3 mounting screws. Finally, check that no terminals touch adjacent circuits before powering up.

Energy Discharge and Safety Notice

This GE DS200IPCSG1A DS200IPCSG1ABC IGBT Snubber Card 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 card 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. The series diode may fail short under extreme reverse voltage conditions.
