Siemens 6RA8028-6FV62-0AA0 Frequency Converter

Siemens SINAMICS DCM DC Converter 6RA8028-6FV62-0AA0 is a four-quadrant DC converter designed for SINAMICS drive systems. It accepts 480 V three-phase AC input at up to 75 A and delivers a regulated DC output of 500 V at up to 90 A, configured with a controllable field rectifier (D500/90). This model belongs to the SINAMICS DCM family (DC Master) and is specified for four-quadrant operation (B6), enabling bidirectional power flow in demanding industrial drives. Typical applications include 480 V three-phase systems requiring robust DC bus power for motors in conveyors, pumps, and processing equipment where both forward and reverse torque with energy handling are needed. The 6FV62-0AA0 designation identifies the DC Master/DCM DC converter variant compatible with the 6RA8028 series, delivering reliable performance under high-current conditions while remaining compatible with Siemens SINAMICS components.
