Product description

The Siemens 6RA8086-6KS22-0AA0 is a SINAMICS DCM (Digital Current Multi-axis) DC converter designed for two-quadrant drive applications. It features a B6C connection and operates with a 3-phase AC input voltage of 690V, drawing up to 598A. The converter includes a controllable field rectifier (D830/720 MRE-GEEF6S22) and provides a DC output voltage of up to 830V and a continuous output current of 720A.

This DC converter is ideal for demanding applications requiring precise control of DC motors, such as rolling mills, extruders, and large material handling systems where regenerative braking or precise speed control is essential. Its two-quadrant operation allows for both motoring and generating modes, enhancing energy efficiency and operational flexibility.

Frequently asked questions

What does 'two-quadrant operation' mean for the Siemens 6RA8086-6KS22-0AA0 DC converter?

Two-quadrant operation means the converter can control the motor in both the motoring (supplying power to accelerate) and generating (acting as a brake, feeding power back to the supply) modes. This allows for precise speed control and energy recovery.
