I/O modules

The complete model DS200IQXSG1A DS200IQXSG1AAA protects inverter circuits from voltage spikes in Mark V systems. This board absorbs transient energy during semiconductor switching events. It extends the operational life of power transistors significantly.

Technical Specifications

Snubber Protection Features

DS200IQXSG1A DS200IQXSG1AAA provides six independent snubber channels for inverters. Twelve capacitors store and dissipate harmful switching energy safely. Twelve resistors limit inrush current during each snubbing event. The board resides in R1 Core location 4. This placement positions it close to the main inverter cards.

DS200IQXSG1A DS200IQXSG1AAA absorbs voltage transients from IGBT switching operations. Six fast-recovery diodes provide freewheeling paths for inductive currents. The board reduces electromagnetic interference from power circuits. Each channel operates independently without cross-coupling effects. This design ensures reliable protection for all six inverter phases.

Operational Integration

The snubber board works with main inverter cards seamlessly. It prioritizes high-frequency switching noise suppression first. DS200IQXSG1A DS200IQXSG1AAA dissipates transient energy as heat gradually. All six channels see active use in three-phase inverter configurations. The board handles continuous switching up to several kilohertz.

Physical and Installation Notes

Manufacturers reference manual GEH-6168 for all installation steps. Each DS200IQXSG1A DS200IQXSG1AAA unit undergoes complete functional testing. We clean every board thoroughly before final shipment. The secondary code DS200IQXSG1AAA appears on the factory identification label. This board weighs approximately 0.9 pound for secure rack mounting.
