6RA7095-4LS22

The Siemens SIMOREG 6RA7095-4LS22 functions as a DC converter that operates in a single-quadrant mode. It features a B6C input circuit, characterized by a 6-pulse bridge design, that connects to a three-phase AC input voltage of about 830 V. The device efficiently converts this input into a DC output voltage that ranges from approximately 830 V up to 1000 V.

It boasts a continuous DC output current rating of around 1900 A, thus ensuring reliable performance under substantial loads. The US rating current of 1400 A is derated to accommodate specific operational limitations. For its field rectification functionality, this converter employs a matched D-series module.

Regarding field supply capabilities, the unit accepts an input of roughly 460 V and can supply around 375 V while delivering 40 A output. Control functionality is managed by a digital microprocessor, enhancing operational precision and responsiveness.

One of the notable features of the 6RA7095-4LS22 converter is its capability for multi-unit applications. It supports parallel and multi-pulse connections, facilitating greater scalability and operational efficiency. Optional fault modules can be included for enhanced protection, ensuring system safety in critical applications. Additionally, it includes a 24 V DC auxiliary supply to power electronic components, reinforcing its functionality and adaptability.
