Siemens 6RA8028-6DS22-0AA0 SINAMICS DCM 400V 75A to 485V DC 90A Two-Quadrant DC Converter
SINAMICS DCM two-quadrant DC converter, B6C, 400V 3AC 75A in, 485V DC 90A out, 15.0 kg
Description
About the 6RA8028-6DS22-0AA0
About the 6RA8028-6DS22-0AA0
The Siemens 6RA8028-6DS22-0AA0 is a SINAMICS DCM two-quadrant DC converter with a B6C bridge connection, rated for a 400 V 3AC, 75 A controllable input and a 485 V DC, 90 A output through the D485/90 MRE-GEE6S22 field rectifier. It weighs 15.0 kg and is manufactured in China.
Selection Notes
The two-quadrant B6C topology gives controlled motoring and regenerative braking into the DC bus without a fourth quadrant, so it fits drives that need controlled deceleration rather than full four-quadrant reversing torque. The 90 A output through the D485/90 field rectifier sizes this unit for roughly 40 kW-class DC motor loads at 485 V; installations with higher current demand should look at the higher-current SINAMICS DCM converter in the same B6C family.
Applications
Thyristor-based control of separately excited DC motors in two-quadrant duty such as extruders, winders, and conveyors where controlled ramp-down is required but full regenerative reversing is not.
