Siemens SINAMICS DCM DC converter
The SINAMICS DC MASTER series of converters includes the DC Converter and Control Module product versions. The DC Converter includes built-in units for connection to a three-phase supply. These are used to supply the armature and field of variable-speed DC drives. The rated DC current range of the units extends from 15 to 3000 A and can be increased by connecting DC Converters in parallel. Depending on the application, units for two-quadrant or fourquadrant operation and with integrated field power section are available. The units are autonomous as a result of the integrated parameterizing device and do not require any additional equipment for parameterization. All functions associated with openloop and closed-loop control, as well as all monitoring and auxiliary functions, are handled by a microprocessor system. Setpoints and actual values can either be entered as analog or digital values. The SINAMICS DC MASTER Control Module is the successor of the SIMOREG CM and is mainly used to retrofit and modernize DC drives.
