The interface to the power part of the converter modules size H6 … H8 from 900 A up to 5200 A consists of one
or two firing pulse transformer boards SCDS-PIN-H41.
Single bridge converters (2Q) are equipped with one board. Converters with 2 anti-parallel bridges (4Q) require
two boards.
Location of the SDCS-PIN-H41
Size H6:
– The board is located inside the converter module.
Module sizes H7 and H8 consist of a control unit and a power unit:
– The board is located inside the power unit.
Module sizes H7 and H8 consist of a control unit and a power unit. The board provides the interface between
control unit and power unit using fiber optic cables.
Following connectors are available
Fiber optic connectors V1, V2 connect the SDCS-CON-H01 via SDCS-DSL-H1x for control.
Fiber optic connectors V11, V12 connect the SDCS-CON-H01 via SDCD-DSL-H1x for Safe Torque Off (STO).
Maximum length of the plastic optic fiber cable is 5 m.
Connector X4 is a connection point for a scope to measure the armature current directly over the burden
resistor.
The Galvanic isolation is an option for
converters size H6 … H8 and rated
voltages 1000 V.
For converters with a rated AC
voltage of > 1000 V or
12-pulse serial > 2 x 500 V galvanic
isolation must be used.
It is used to replace the high-ohmic
voltage measurement and gives the
advantage of a total isolation between
power part and drive electronics.
The transformer T90 and the
DC-DC transducer A92 are located
outside the converter module. The
internal AC and DC voltage
measurement channels are removed
and connected to T90 and A92.
