- Description
The Siemens 6RA8018-6DV62-0AA0 is a SINAMICS DCM DC converter with a 4-quadrant, B6A(B6)C circuit, rated for 25 A at 400 V 3AC input and 420 V DC at 30 A output. It uses the D420/30 MREQ-GEG6V62 field rectifier to supply the separate field winding and weighs 11.0 kg. It supplies armature power for DC motor drives in the SINAMICS DCM series.

Selection Notes
The 4-quadrant B6A(B6)C circuit uses two anti-parallel three-phase bridges, so this converter can motor and regenerate through the armature circuit without contactor reversal, useful whenever the load needs active braking or hoisting duty. At 25 A input and 30 A output it covers the low end of the SINAMICS DCM range.
