Siemens 6RA70/28 DC converter 
 Outline 

 SIMOREG 6RA70 Series three-phase rectifier power supply directly to all-digital control device, its compact, variable speed DC for armature and field supply, the rated current range of 15 ~ 2200A, and through parallel SIMOREG rectifier device expansion. 

 Depending on the application, choose to work alone or 4-quadrant device, the device itself with a parameter setting unit, without any additional equipment other parameters set to be completed. All the control, regulation, monitoring and realization of additional functions by the microprocessor. Choose a given value and the feedback is digital or analog. 

 SIMOREG 6RA70 series rectifier is characterized by small size, compact structure. The door is equipped with an electronic device box, box into the regulation board, the electronic box can be installed for technical expansion and additional serial interface board. Unit is easy disassembly so that each device service simple and easy.
