Microprocessor Controlled Four-Quadrant Operation High DC Output Current (125A) Regenerative Capability Controllable Field Rectifier Robust Industrial Design

Product description

The Siemens SIMOREG DC Master 6RA7031-6FV62-0 is a sophisticated DC rectifier unit equipped with a microprocessor for advanced control of four-quadrant drives. It utilizes a B6 (six-pulse) bridge configuration for efficient power conversion. The unit features a 460V 3AC input and provides a controllable output of 480V DC at 125A (US rating 500V DC, 100A).

This rectifier is designed for demanding applications requiring precise and bidirectional control of DC motors. Its four-quadrant capability allows for both motoring and generating operation, making it suitable for applications like rolling mills, extruders, and winches where regenerative braking is utilized. It also includes a field rectifier output (D480/125) with specifications for 480V DC, 100A output, and a field output of 375V, 10A.

Frequently asked questions

What does 'four-quadrant drives' mean in the context of the Siemens 6RA7031-6FV62-0 rectifier?

Four-quadrant operation means the drive can operate in motoring (positive torque, positive speed) and generating (negative torque, positive speed) modes, as well as reversing these directions. The Siemens SIMOREG DC Master 6RA7031-6FV62-0 supports this bidirectional power flow for advanced DC motor control.
