About the IS200DAMBG1ABB
As a board included in the Innovations Series 200DAM_ Gate Drive Amplifier Interface Boards, the IS200DAMBG1ABB board provides a convenient interface between a control rack interface and a power switching device, which are called the IGBTs. The DAMA boards is a 620 frame board with a CM1000HA-28H Powerrex IGBT and three boards per drive, with only one board for each individual phase leg. Also, there is only one IGBT included for the device’s upper phase leg and only one IGBT included for the device’s lower phase leg. The DAM_ boards connect right to the IGBT collector terminals, gates, and terminals and directly with the IS200BPIA Bridge Personality Interface board, which is found within the control rack. Additionally, there are no testpoints, fuses, or configurable items anywhere on the board.
IS200DAMBG1ABB Connections and Variations
There are multiple IGBT Connection pins in the IS200DAMBG1ABB, each with their one name and description. Pin 1 is named GLIN, which is intended to be the lower gate signal. Pin 2 is named LCOM and is intended to be the lower common signal (emitter). Pins 3, 4, 8, and 9 are named NC and they are not connected. Pin 5 is named CL and is intended to be the lower collector signal. Pin 6 is named UCOM and is intended to be the upper common signal (emitter). Pin 7 is named GUIN and is intended to be the upper gate signal. Pin 12 is named CU and is intended to be the upper collector signal. This IS200DAMBG1ABB device is actually not even considered the originally-developed device version of its particular Mark VI Turbine Control System Series intended functional role. The original Gate Drive Amplifier Interface Board of this specific functionality is the IS200DAMBG1 parent PCB product notably not utilizing any one of this IS200DAMBG1ABB device's three significant product revisions. This six different variations of gate drive boards allotted to General Electric's esteemed Mark VI Series include the:
- 620 frame DAMA Board
- 375 frame DAMB Board
- 250 frame DAMC Board
- G1 for 180 frame, G2 for 125, 92 for G2 frame DAMD Board
- 65 frame DAME Board
