Siemens 6RA8018-6FV62-0AA0-Z G00G20S01 DC Converter

Siemens 6RA8018-6FV62-0AA0-Z is a SINAMICS DCM DC Converter designed for four-quadrant drive configurations (B6). It accepts three-phase AC input in the 400–480 V range and typically draws about 25 A, delivering a DC output rated up to 30 A. The nominal DC bus voltage depends on the exact variant, with documentation listing outputs around 420 V DC or 500 V DC. As part of the SINAMICS DCM family, this module enables four-quadrant operation for motors with regenerative braking, providing the DC link power required by SINAMICS DCM drive architectures. This converter is used in industrial automation environments to power servo and DC motor drives that require bidirectional torque and controlled DC power delivery. The 6RA8018-6FV62-0AA0-Z sits in Siemens’ lineup of DC converters for 480 V three-phase systems and is intended for integration with SINAMICS DCM controllers and drive hardware that support four-quadrant operation.
