Siemens 6RA8013-6DV62-0AA0 SINAMICS DCM DC Converter 400V AC / 420V DC 15A 4-Quadrant B6

The Siemens 6RA8013-6DV62-0AA0 is a SINAMICS DCM DC converter configured for 4-quadrant operation using a (B6)A(B6)C antiparallel thyristor bridge circuit. It accepts 400 V 3AC input at 13 A and delivers a controlled 420 V DC output at 15 A, with an integrated field rectifier rated D420/15 (MREQ-GEG6V62) for separately excited DC motor field supply.

Selection Notes

The 6RA8013-6DV62-0AA0 targets separately excited DC drives up to 15 A armature current at 420 V DC — a rating suited to small DC motors in the range of approximately 4–6 kW depending on efficiency. The (B6)A(B6)C dual-bridge topology enables true 4-quadrant operation: the converter can both supply and absorb armature current in both rotational directions, making regenerative braking into the mains possible without a mechanical brake or external braking chopper. Compared to the 2-quadrant (B6)C single-bridge siblings in the SINAMICS DCM range, this variant is the correct choice wherever reversing duty or fast dynamic braking is a process requirement. The integrated D420/15 field rectifier eliminates a separate field supply unit, reducing cabinet footprint for this output class.

Applications

Typical applications include reversing winders, test benches requiring four-quadrant torque control, extruder drives with regenerative deceleration, and small DC spindle drives on legacy machine tools where an AC retrofit is not viable. The 400 V 3AC input matches standard European industrial supply without an additional transformer at this power level.
