Siemens 6RA8028-6DV62-0AA0 SINAMICS DCM D420/90 400V 3AC 75A to 420V DC 90A 4Q DC Converter
SINAMICS DCM 4-quadrant DC converter, 400V 3AC 75A input, 420V DC 90A output, D420/90 field rectifier.
Description
About the 6RA8028-6DV62-0AA0
About the 6RA8028-6DV62-0AA0
The Siemens 6RA8028-6DV62-0AA0 is a SINAMICS DCM 4-quadrant DC converter in B6A(B6)C circuit configuration, rated for 400 V 3AC 75 A input and delivering 420 V DC at 90 A to the armature, with a D420/90 field rectifier (MREQ-GEG6V62) for the motor field winding. It weighs 15.0 kg and is manufactured in China.
Selection Notes
The (B6)A(B6)C 4-quadrant circuit means this converter can both drive and regeneratively brake the DC motor, feeding energy back to the AC line instead of dissipating it in a braking resistor, which is the deciding factor over a 2-quadrant B6C unit for hoist, crane, or winder duty with frequent reversing loads. The integrated D420/90 field rectifier supplies the separate field winding of the DC motor, so no external field supply is needed for a standard separately excited motor. At 90 A armature output this unit sits toward the lower-current end of the SINAMICS DCM range; higher-current variants exist for larger motors in the same family.
Applications
Armature and field control for separately excited DC motors in crane, hoist, winder, and other regenerative drive retrofits requiring 4-quadrant operation from a 400 V 3AC supply.
