SDCS-CON-2A  DCS Thyristor Power Converters

General remarks
The term “DCS thyristor power converter” is a general designation for basic DC converters from ABB. This term
can be found in many parts of the relevant documentation. The precise product name in accordance with the
brief descriptions given below characterizes a specific unit.
Brief description of DCS 500 and DCS 500B
The DSC 500B unit range is an enhancement developed from the DCS 500 range. The difference between the
two ranges lies in the version of the control board: the control board used for the DCS 500B unit range is the
SDCS-CON-2 type, which is different from the SDCS-CON-1 type in several points (see the table below).
Brief description of DCP 500 and DCP 500B
In the DCP 500 unit, the electronics of the DCS 500 unit have been equipped with a different power section,
which changes its visual appearance, its installation dimensions and the interface between the power section
and the electronics. The DCP unit is functionally compatible with the DCS unit, since the electronics (power
pack, control board and options and/or control) are identical. The DCP 500B unit range is an enhancement
developed from the DCP 500 range, with the difference between the two ranges lying in the control board: the
control board used for the DCP 500B unit range is the SDCS-CON-2 type, which is different from the SDCSCON-1 type in several points (see the table below).

SDCS-CON-2A

Brief description of DCF 500B
With software release 21.232 or higher DCS 500B has a ‘3-phase field exciter mode’. A DCF 500B is

a threephase field exciter based on the programmable DCS 500B software and the SDCS-CON-2 control board.
The interface boards PIN-1x/PIN-2x are modified; – an overvoltage protection unit DCF 505/506 is required.
Brief description of DCS 600
The DCS 600 converter family is based on the hardware developed for the DCS 500B type.
Instead of a COM-x board, the SDCS_AMC_DC board is used. PC tools will be connected there, as well as
the APC (Application controller), if the APC is used as a PLC. If a different PLC is used, separate adapter
modules are needed. They must be connected to the AMC-DC board, too. The software code always begins
with S15.xxx for MultiDrive or S18.xxx for Crane drives.
Brief description of DCF 600
The DCF 600 unit range is intended to be used for supplying motor fields and is based on the hardware and
system configuration of the DCS 600 unit. The software is identical to the DCS 600 software. Similar to DCF
500 units the DCF 505/506 overvoltage protection unit is required. The same modification is applied to the
PIN-1x/PIN-2x boards, compared to DCF 500.
Brief description of DCS 400
The DCS 400 is the smallest drive in its class. The compact design has been partly achieved by a fully integrated
field exciter based on IGBT technology. A commissioning wizard – available on the control panel and the PC
tool – makes start-up of the drive easy. In addition, the DCS 400 contains application macros.
