Product Description
The IS200DSFCG1ACA is a combination IGBT Gate Driver/Shunt Feedback board from the Mark VI Speedtronic line. This series of circuit boards originally manufactured by General Electric were used in association with gas and steam turbine control systems. The IS200DSFCG1ACA is rated at 1000/1800 amps. It includes a fault detection circuit along with two IGBT gate drive circuits and a current sensing circuit. Both the feedback and driver circuits have been optically and galvanically isolated.
The IS200DSFCG1ACA is a nearly square circuit board with four factory-drilled mounting holes, one per corner. There are additional eyelet connectors throughout the body of the board. The board also features stab-on and plug connectors for output phase voltage sensing and DC link voltages.
Additional components on the IS200DSFCG1ACA include five LED indicators marked DS1 through DS5, which display the DC link and IGBT driver status. The board is also populated with resistors and resistor network arrays, capacitors, a transformer, over twelve integrated circuits, and three transistors. There are two LED colors on the DSFC board. The yellow LED indicates when the IGBTS are on or off; when the LED is on, it indicates that the IGBTS are driven on. The green LED will be on when the IGBTs are driven off.
For additional information about the IS200DSFCG1ACA, including detailed information regarding proper installation and handling procedures, please refer to the GEI-100263 instruction manual. The manual also contains a block diagram of the DSFC board, which is located on page three of the manual.
