SD700FL Series VSD

The unique features of the SD700 drive are improved by adding an input notch filter that reduces the THDi below 5%. It is constructed through the parallel connection of individual filtering modules, all controlled and monitored by the drive. Each module has a contactor that isolates the long-life integrated capacitors. These unique features makes it suitable for any low harmonic application. 

Available in 400V and 690V, 2.2kW – 1800kW.

A premium low harmonics drive offer

The SD700FL series extends the outstanding features of the SD700 series by adding an input notch filter that reduces the THDi below 5%. It is constructed through the parallel connection of individual filtering modules, all controlled and monitored by the drive. Each module integrates temperature sensors, a MCCB to protect the long life integrated capacitors and a contactor that isolates the capacitors when the filter isn’t running. What makes SD700FL different? The filtering features do not depend on the grid impedance, that means that the filter will never cause resonance like a tuned passive filter could, and its performance will not vary significantly after electrical grid modifications. This feature makes it suitable for any low harmonic application.

  • Input current harmonics below 5% at 100% load. Input displacement power factor >0.99 at 100% load.
  • Very low capacitive reactance makes the Freemaq suitable for operation on generators.
  • Capacitor isolation contactor ensures the capacitors are disconnected from the supply when the SD700 is not running. There is no unwanted reactive power consumption on the network that risks pushing the electrical system into a leading power factor.
