Gen-set controllers RGK900 series

January 8, 2015

The RGK900 from Lovato is designed with control and protection in mind. The device is best suited to synchronising and load shedding operation related applications.

While it still has all the celebrated features of the RGK700 and RGK800, it also boasts a range of new ones that help expand and improve on its already impressive functioning.

Applications:

  • Single generator in maintained parallel with the mains in “base-load” mode

     (Generator power supplied at a steady rate)

  • Single generator in maintained parallel with the mains, in peak-shaving mode

    (Import-export – mains power is limited to constant value and load peaks during heavy demand for power are supplied by generator)

  • Single generator in AMF with temporary parallel with the mains

           (For emergency, with AMF in closed transition).

You can find this innovative product, and more, in the ElectroMechanica catalogue page F-2
