6RA7086-6KS22-0

The Siemens 6RA7086-6KS22-0 model is a specialized DC converter ideal for single-quadrant operations. Accepting a three-phase AC input of approximately 690 V, it generates a significant DC output voltage of about 830 V, coupled with a substantial output current rating of 720 A. This converter effectively handles continuous power levels nearing 600 kW, sufficient for high-demand industrial tasks.

The design incorporates a 6-pulse bridge topology, ensuring efficient power conversion while operating exclusively in the first quadrant without regenerative capabilities. Active protection measures include overcurrent and short-circuit safeguards, which enhance the safety and reliability of operations.

Installation is straightforward due to its chassis mount configuration, and it utilizes an external cooling mechanism for effective thermal management. The control is executed via a digital closed-loop system, which provides precise control over performance parameters. With options for both analog and digital I/O interfaces, flexibility in communication with various systems is assured. Weighing in at approximately 44 kg, this unit is also designed for compatibility in parallel setups, making it versatile for scaling up to meet larger power demands.
