Siemens 6RA7078-6FV62-0-Z DC Converter 500VDC 210A

Siemens SIMOREG DC MASTER converter 6RA7078-6FV62-0-Z is a microprocessor-based DC drive converter designed for four-quadrant drive configurations, delivering precise, controllable DC power from a 460V three-phase supply while integrating with the drive system’s field and control circuitry. It outputs 480V DC at up to 280A continuous, with a US-rated DC output of 500V DC at 210A, a specification that supports robust startup torque and sustained torque across a wide speed range for large industrial DC motors. The unit's input specification is 3-phase 460V AC with 233A controllable, and it uses a field rectifier module D480/280 (MREQ-GEGF6V62); the field input requirement is 15A at 460V AC, two-phase, 50/60 Hz, illustrating the dedicated field-supply architecture. As part of the SIMOREG DC MASTER family, the 6RA7078-6FV62-0-Z is engineered for demanding industrial environments where reliable four-quadrant DC motor control and integrated safety and control features are essential.
