6RA7088-6LS22-0

The Siemens 6RA7088-6LS22-0 DC rectifier operates effectively in single-quadrant configurations. As a 12-pulse B6C rectifier, its design allows it to accept an AC input of 830 volts from a three-phase supply. Simultaneously, it generates a DC output voltage of 1000 volts and can handle output currents of up to 900 amperes. The device is well-suited for applications requiring a strong field supply, offering 375 volts DC at a current of 30 amperes.

This model can operate within a power range of 6 to 2500 kilowatts, making it adaptable for various needs. Its user interface is managed via a PMU panel, providing straightforward operational control. To maintain optimal performance, cooling is handled through a forced-air system, which aids in managing thermal dissipation effectively. The allowable ambient limits for this unit span from 0 to 45 degrees Celsius and can function at altitudes of less than 1000 meters.

For monitoring purposes, the rectifier includes thermal and current sensors, ensuring operational safety and efficiency. The structural design allows for cubicle chassis mounting and supports parallel use in setups requiring multiple units. Furthermore, this rectifier is equipped with protections against overcurrent conditions, as well as I²t, enhancing its reliability and safety in industrial settings.
