Area of application
The SINAMICS DC MASTER converter units have been specifically designed to supply the
armature and field of DC motors.
Alternative applications (e.g. supplying the field of a synchronous generator) are also
possible.
Design
SINAMICS DC MASTER converter units are compact units containing both the power unit for
the armature supply and the power unit for the field supply, as well as the control electronics
and possible additional modules.
In the case of units with a 15 A to 1200 A rated DC current, the power units for the armature
and field include electrically insulated thyristor modules, meaning that the heat sink is at
ground potential. In units with a higher rated DC current, the power unit for the armature
circuit includes disc-type thyristors and heat sinks (thyristor modules) at voltage potential.
The units have degree of protection IP00.
The connecting terminals are accessible from the front. The fan supply is fed in from the top;
depending on the unit type, the field supply is either fed in from the top or the bottom.
All SINAMICS DC MASTER units are equipped with a Basic Operator Panel BOP20 in the
front plate.
The following conditions are enabled with the BOP20:
● Settings required for commissioning
● Display for all relevant measured values
● Display of faults and alarms and acknowledgment of faults
● Switching the drive on and off
