DS200ITXDG1ABA

Product Description

The DS200ITXDG1ABA board is labeled as a Dynamic Braking Snubber Board as part of the Mark V series made by General Electric. The operation required for the IXTD board is provided through the circuits of the connected power supply/interface board (IMCP). When the IMCP and the IXTD boards are connected they are connected through a four-pin connector. When the board is mounted it will be mounted externally and must be sized to meet the worst-case switching demands of the dynamic braking IGBT. The purpose of snubber boards is to be used to limit the voltage transients across the IGBTs and through all known operating conditions of the drive.

Another ability of the DS200ITXDG1ABA board is to condition outputs from the IGBT Gate Driver Board to be able to match the electrical properties of the AT frame drives. There are variable and constant torque applications for the AT frame drives. The drive-rated output current for the variable torque applications is five hundred ARMS. 

There are three connector types for the DS200ITXDG1ABA board; bus bar I/O connectors, input connectors for the DBPL, and board stab connectors. There are different pin numbers, nomenclatures, as well as descriptions for all of these connector types. The bus bar I/O connectors and stab I/O connectors have directions as well. An example of two pins related to the stab I/O connectors are the E-6 and E-9 connectors, both are output connectors. The E-6 connector is the DB IGBT gate signal, and the E-9 connector is the connection for the external snubber resistor.
