TP830 3BSE018114R1 base module

The power interface board is used for DCS 500 converter modules models C1 and C2. There are different versions in use. The used types are: - SDCS-PIN-21 for 100 A...350 A Converters at 500 V - SDCS-PIN-22 for 450 A...520 A Converters at 500 V ➀ - SDCS-PIN-23 for 110 A...270 A Converters at 600 V - SDCS-PIN-24 for 450 A Converters at 600 V ➀ - SDCS-PIN-25 for 700 A Converters at 500 V ➀ at these boards the SDCS-PIR-21 is used Resistors R112, R114 and R116 are fitted with MOV elements on the SDCS-PIN-23/24, and on all other PIN-boards with 0-
resistors. The SDCS-PIN-2x board consists of: - firing pulse circuits with pulse transformers - measurement of the armature current - snubber circuit for thyristors protection (consists of RC circuits and MOV elements) - AC and DC high ohmic voltage measurement - scaling for rated current, zero current detection and HW voltage type coding - interface for heat sink temperature measurement Fig. 5.2/1 Layout of the SDCS-PIN-2x board. with a PTC sensor - fuses for overvoltage protection and voltage measuring - If the SDCS-PIN-21/22 connection board is installed in a DCF50x-0100...0520 / DCF60x0100...0520, then the components R112, R114 and R116 are not build-in Note: If this PCB is used as a spare part for a DCF.... , then the resistors R112/R114/R116 (value = 0
) must be removed.

Spare part 

The protection of the power part is done by using RC circuits and MOV elements. Snubber circuits are wired up in parallel to each thyristor directly without fuses in between. In addition to that MOV elements are wired up in between the phases and protected by the fuses F101 to F 103. The AC voltage measurement is taken from behind the fuse. Fuse data: Bussmann KTK-R-6A (600V)

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 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. Fuse data: Bussmann KTK-R-6A (600V) 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).

Power interface board SDCS-PIN-20x

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
