SDCS-PIN-205B 3ADT312500R0001

The power interface board is used for DCS con- verter modules construction type C1 and C2. There are different versions in use. The used types are: - SDCS-PIN-205B for 100 A...1000 A Conv. at 500 V including the 3-phase field supply converters DCF... - SDCS-PIN-206B for 110 A...450 A Conv. at 600 V The SDCS-PIN20xB can replace the SDCS-PIN- 20x and PIN-20xA but not vice versa. 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 - the same board will be used without any modifi- cation 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 in parallel to each thyristor with fuses in between. RCD ele- ments 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 re- placement of SDCS-PIN-23 and 24, but not vice- versa! In case of a converter with 450 A / 520 A / 700 A at 500 V or a converter of 450 A at 600 V ad- ditional actions have to be taken into account. Note If this PCB is used as a spare part for a DCF..., no modifications are necessary.
