Two-quadrant DC drive control B6C connection 480V 3-phase input 575V DC 280A output Field rectifier control High-performance DC conversion

Product description

The Siemens SINAMICS DCM (Digital Current Multi-axis) converter, part number 6RA8078-6FS22-0AA0-Z, is a high-performance DC converter designed for two-quadrant drives. This unit features a B6C connection (six SCRs in a bridge configuration) and operates with a 480V 3-phase AC input, drawing up to 232A. The controllable output is managed by a D575/280 MRE-GEEF6S22 field rectifier, providing a DC output voltage of 575V and a continuous output current of 280A.

This SINAMICS DCM converter is ideal for applications requiring precise bidirectional control of DC motor drives. Its two-quadrant operation allows for motoring and generating (braking) modes, making it suitable for demanding applications such as rolling mills, coiling machines, extruders, and other industrial machinery where regenerative braking is utilized.

Stanlo Automation, a veteran-owned surplus industrial parts distributor, offers the Siemens SINAMICS DCM DC converter. Equip your critical machinery with reliable and powerful DC drive solutions from Stanlo Automation.
