Product description

The Siemens 6RA7085-6GV62-0 is a SIMOREG DC Master rectifier equipped with a microprocessor for advanced control of four-quadrant drives. It features a robust design with a B6 (B6) C circuit configuration. The input power is 575V 3-phase AC at 498 Amps, and it provides a controllable output of 600V DC at up to 600 Amps. This unit also includes specifications for a D600/600 MREQ-GEGF6V62 field rectifier and a 460V field input providing 375V at 25A output.

This rectifier is engineered for demanding DC drive applications that require precise speed and torque control in both directions of rotation. Its four-quadrant capability allows for energy regeneration back to the supply line during braking. Applications include heavy industry, rolling mills, paper machines, and other complex motion control systems where high power and dynamic performance are essential.
