Pulse transformer board SDCS-PIN-48
This board is always required with the rebuild kit.
Normally one SDCS-PIN-48 board per 6 thyristors, if the board can be placed
close (gate wires <1 m) to all 6 thyristors of one bridge.

Wiring
The gate-cathode wires, which are a part of the rebuild kit's delivery, have to be
handled in this way:
-
One end is equipped with a coded plug, which fits the C and G pins on the
SDCS-PIN-48
-
The cable length in the delivery condition is 2 m. The cable routing should be
done, to end up with a cable length as short as possible; the max. cable length
is 1 m. The cables have to be shortened and have to be equipped with the plug
connector, demanded by the thyristor type in use.
