MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200IAXSG1A DS200IAXSG1ABB IGBT Snubber Board suppresses voltage spikes across IGBT switches. This board mounts directly adjacent to the main IGBT power modules. You will find it protecting semiconductors during high-speed turn-off events. It significantly extends the operational lifetime of expensive power devices.
Core Technical Specifications
The GE DS200IAXSG1A DS200IAXSG1ABB IGBT Snubber Board measures 27.0 cm in width and 19.0 cm in height. Its board depth equals 4.0 cm including capacitor and resistor components. The total assembly weighs approximately 1.2 kilograms. Six independent snubber circuits occupy the board’s surface area. Each circuit protects one IGBT in a three-phase bridge configuration.

Connectors and Bus Bar Interfaces
The GE DS200IAXSG1A DS200IAXSG1ABB IGBT Snubber Board uses heavy-duty ring terminals for power connections. Two copper bus bars connect the board directly to IGBT collector and emitter terminals. Six 2-pin headers provide gate driver feedback signals to the control board. Additionally, the board includes one 9-pin connector for thermistor monitoring.
Energy Storage Discharge and Safety
Each snubber capacitor stores up to 0.49 joules of energy at 1200 VDC. Therefore, this board retains dangerous energy long after power removal. You must wait 5 minutes for capacitors to discharge fully. The GE DS200IAXSG1A DS200IAXSG1ABB 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 or wire.
Thermal Management and Mounting
This snubber board requires vertical mounting for proper convective cooling. The power resistors generate significant heat during normal drive operation. Maintain at least 5 cm clearance around each resistor body. Moreover, the GE DS200IAXSG1A DS200IAXSG1ABB IGBT Snubber Board operates from 0°C to +60°C ambient temperature. Use 10 AWG wire for all external power connections. Do not operate the drive with a missing or damaged snubber board. Replace the board immediately if capacitors show bulging or leakage signs.
