DC Converter
The series of SINAMICS DC MASTER DC Converters includes the following components:
Electronics module with Control Unit (CUD) and slot for expansionusing another CUD (in a cradle that can be swiveled out)
Power section with thyristors in a fully-controlled three-phasebridge circuit configuration (two-quadrant drive: B6C or fourquadrantdrive: (B6) A (B6) C) 1)
Fan (up to 125 A: self-ventilated)
Single-quadrant field power section with integrated freewheelingcircuit (optionally, also without field or as twoquadrantfield for highly dynamic field current changes withintegrated field overvoltage protection)
Electronics power supply
Standard BOP20 operator panel (AOP30 Advanced OperatorPanel as accessory)
1) In two-quadrant operation, the drive can operate in "driving" mode in one direction of rotation and in "braking" mode with regenerative feedback in the opposite direction of rotation. In four-quadrant operation, the drive can operate in "driving" mode and in "braking" mode with regenerative feedback in both directions of rotation.
