Siemens 6RA8091-6DV62-0AA0 SINAMICS DCM Four-Quadrant DC Converter 400V AC 996A / 420V DC 1200A
Siemens SINAMICS DCM four-quadrant DC converter, 400V 3AC 996A in / 420V DC 1200A out, (B6)A(B6)C bridge.
Description
About the 6RA8091-6DV62-0AA0
About the 6RA8091-6DV62-0AA0
The Siemens 6RA8091-6DV62-0AA0 is a SINAMICS DCM four-quadrant DC converter for DC drives, rated for 420V DC output at up to 1200A from a (B6)A(B6)C anti-parallel thyristor bridge pair. It is supplied from a 400V 3AC line drawing up to 996A and includes field rectifier D420/1200 (MREQ-GEGF6V62) for separate field excitation of the DC motor.
Selection Notes
This unit pairs two anti-parallel (B6)A(B6)C thyristor bridges, so current can reverse direction and the converter can both motor and regenerate across all four torque/speed quadrants. That makes the 6RA8091-6DV62-0AA0 the right choice at 1200A output where the load needs regenerative braking or frequent reversal, such as hoists, winders, or reversing mill stands, rather than the two-quadrant variant at the same current rating, which cannot return energy to the line.
