Variable Speed Drive

Our VSD’s are essentially frequency inverters, with the main function to increase or decrease the speed of the motor connected to the pump, by altering the frequency. This adjustment in frequency results in the pump achieving a required duty at a given point in time to fit the application that it was designed for. The VSD can be preset according to this dutypoint. We offer a range of VSD’s from 0.75kW up to 45kW in three phase 220V (up to 2.2kW), 380V and 525V. Protection that the VSD’s include is Overload, Low- & High Voltage, Instant Stop/Start, Stall Prevention, Output Short Circuit etc.
