Features:
- Power-stage interface: carries firing-pulse, measurement, and protection functions.
- Current range: documented for applicable 25 A, 50 A, and 75 A converters.
- Spare configuration: resistor setup changes are required for specified DCF applications.
SDCS-PIN-11 3ADT306100R1 links converter control circuits to the thyristor power stage and its measurement paths.
The board combines firing-pulse transformation with current, voltage, zero-current, and heatsink-temperature feedback functions.
A spare must be configured for the exact converter family before startup; visual similarity is not sufficient.
Apter Power supports document review, quotation, and procurement for the ABB SDCS-PIN-11 3ADT306100R1 Power Interface Board.
