MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200IPCDG2A DS200IPCDG2ABA IGBT Snubber Board protects IGBT modules from voltage spikes. This board mounts directly next to the main power IGBTs in the drive. You will find it suppressing transient overvoltages during switching events. It extends the operational life of expensive power semiconductors significantly.
Core Technical Specifications
The GE DS200IPCDG2A DS200IPCDG2ABA IGBT Snubber Board measures 26.0 cm in width and 18.0 cm in height. Its board depth equals 3.5 cm including capacitor and resistor height. The total assembly weighs approximately 1.1 kilograms. Four independent snubber circuits occupy the board’s surface. Each snubber circuit protects one IGBT phase leg or braking chopper.

Connectors and Bus Bar Interfaces
The GE DS200IPCDG2A DS200IPCDG2ABA IGBT Snubber Board uses heavy-duty screw terminals for power connections. Two copper bus bars connect the board directly to IGBT collector and emitter terminals. Four 2-pin headers provide gate driver feedback signals to the control board. Additionally, the board includes one 9-pin connector for temperature monitoring.
Energy Storage Discharge and Safety
Each snubber capacitor stores up to 0.72 joules of energy at 1200 VDC. Therefore, this board retains dangerous energy after power removal. You must wait 5 minutes for capacitors to discharge fully. The GE DS200IPCDG2A DS200IPCDG2ABA IGBT Snubber Board includes built-in bleed resistors across each capacitor. These resistors discharge the capacitors to safe voltage levels automatically. Always verify zero voltage before touching any terminal.
Thermal Management and Mounting
This snubber board requires vertical mounting for proper convective cooling. The power resistors generate significant heat during normal operation. Maintain at least 4 cm clearance around each resistor body. Moreover, the GE DS200IPCDG2A DS200IPCDG2ABA IGBT Snubber Board operates from 0°C to +60°C ambient. Use 10 AWG wire for all external power connections. Do not operate the drive with a disconnected or damaged snubber board. Replace the board immediately if capacitors show signs of bulging or leakage.
