This board contains only resistors to increase the
power of the snubber circuit and it is connected by
metal standoffs.
The SDCS-PIR-21 board is used with the following
power interface boards:
- SDCS-PIN-22 450 A/520 A at 500 V
- SDCS-PIN-24 450 A at 600 V The power interface board is used for DCS converter modules construction type C1 and C2. There
are different versions in use. The used types are:
- SDCS-PIN-205 for 100 A...700 A Conv. at 500 V
- SDCS-PIN-206 for 110 A...450 A Conv. at 600 V
- SDCS-PIN-205B for 100 A...1000 A Conv. at 500 V
- SDCS-PIN-206B for 110 A...450 A Conv. at 600 V
The boards are cyclic updated from SDCS-PIN-20x
? PIN-20xA ? PIN-20xB according to the technical
requirements and the new C2 converter types. The
SDCS-PIN20xB can replace the SDCS-PIN-20x
and PIN-20xA.
The SDCS-PIN-20x board consists of:
- firing pulse circuits with pulse transformers
- measurement of the armature current
- snubber circuit for thyristor protection
(consists of RC circuits in parallel of the thyristors
and RCD network)
- AC and DC high ohmic voltage measurement
- rated current scaling with burden resistors, zero
current detection and HW voltage type coding
- interface for heat sink temperature measurement
with a PTC sensor
- fuses for overvoltage protection and voltage
measuring
Fig. 5.2/4 Layout of the SDCS-PIN-20x, 20xA, 20xB board.
- the same board will be used without any modification at a converter used for three-phase field
supply
Spare part
The protection of the power part is done by using
RC circuits. Snubber circuits are wired up in parallel to each thyristor with fuses in between. RCD elements are protected by the fuses F 101 to F 103.
The AC voltage measurement is taken from behind
the fuse.

The power interface board SDCS-PIN205 can be
used as a replacement of SDCS-PIN-21, 22 and
25. The board SDCS-PIN-206 can be used as a replacement of SDCS-PIN-23 and 24, but not viceversa! In case of a converter with 450 A / 520 A /
700 A at 500 V or a converter of 450 A at 600 V additional actions have to be taken into account (the
basic difference between the SDCS-PIN-2x and
PIN-20x is marked by the grey-shaded areas numbered 1,2 and 3 in fig. 5.2/3).
