6RA7081-6DV62-0

The part number 6RA7081-6DV62-0 from Siemens is a SIMOREG DC Master Rectifier. This device is engineered with a four-quadrant drive circuit (B6) A (B6) C configuration, providing versatile functionality in power applications. It is designed to handle an input voltage of 400 volts AC, with a tolerance of ±10%. The input current for this rectifier reaches up to 332 Amps, making it robust for demanding tasks. The input frequency can vary between 50 and 60 Hz, allowing compatibility with different electrical systems.

In terms of performance, the rectifier outputs a substantial 420 V DC and can deliver a maximum current of 400 A. The cooling mechanism utilized for this model is forced air cooling, ensuring effective heat dissipation during operation. This model is built to endure operational environments with ambient temperatures ranging from -10°C to +40°C. For storage, it can withstand extremes from -40°C to +70°C, indicative of its adaptability to varying conditions. It has an IP20 protection rating, suitable for many indoor installations where dust and moisture are concerns but not for direct exposure to water.

Communication capabilities are provided through an RS485 interface or PROFIBUS for flexible connectivity within systems. The design includes safeguards against overloads and short-circuits to protect the equipment during unforeseen circumstances. Additionally, the power factor of 0.9 demonstrates its efficiency in energy usage. With dimensions of 600 mm in height, 600 mm in width, and 300 mm in depth, the 6RA7081-6DV62-0 is designed to fit into standard industrial mounting configurations.
