DCS 500 / DCS 600 Service Manual
Compatibility of thyristor modules for
DCSxxx-0200 and DCSxxx-0250
Types concerned:
DCS500B and DCS600
Actual status
All converter types with rated current 200A and 250A are now e-
quipped with thyristor modules type MCC 95-16io1B.
Hardware:
The thyristor module was changed from: SKKT 106/16 E
(DCA0011931P0001) to MCC 95-16io1B (3ADC340012P0002)
Subject:
The two types of thyristor modules are
not
compatible. The connec-
tors for gate (
G2
) and cathode (
K2
) are exchanged. See also follo-
wing drawing:

Attention:
The connectors of the new firing pulse cable harness fit
on the old thyristor module, but the leads (G2 and K2) for thyristor 2
are exchanged. There is no change for thyristor 1.
The wire for the gate is yellow. The one for the cathode is red.
Spare parts:
For the new converter modules with type code
DCSxxx-xxxx-00-0000000-0000000
3
0
use thyristor modules MCC 95-16io1B.
For the old converter modules with type code
DCSxxx-xxxx-00-0000000-0000000
4
0 or
DCSxxx-xxxx-00-0000000-0000000
use thyristor modules SKKT 106/16E.
Time schedule:
MCC 95-16io1B have been used since:
DCS500B / DCS600:
14.10.2003 with serial number
001941B3406813
Compatibility:
The technical data of new converter modules are the same.
