GE DS200GLAAG1A DS200GLAAG1ACC stores energy using one ceramic capacitor. This capacitor provides 10 µF at 35V rating for gate pulse filtering. Consequently, the board maintains clean firing signals during 5 microsecond transients. Therefore, SCRs receive reliable gate pulses in noisy environments.
Design and Integration
Both the GE DS200GLAAG1A and DS200GLAAG1ACC versions share identical gate driver topology. These boards use four-layer PCB construction with high-voltage isolation between primary and secondary. Consequently, the GE DS200GLAAG1A DS200GLAAG1ACC operates reliably from -10°C to +55°C ambient temperature.
For installation, you need M3 screws for the four mounting holes. The board draws 80 mA typical current from the 24V DC supply. Each gate channel provides isolated drive for individual SCRs. We recommend mounting the board close to the SCR modules for best performance.
Practical Application
This gate lead adapter board connects SCR gate drivers to power semiconductor modules. It transmits firing pulses from the regulator to each thyristor. The GE DS200GLAAG1A DS200GLAAG1ACC also provides LED status indication for each gate channel. Therefore, it simplifies wiring and troubleshooting in DC drive and exciter systems.
