Why a variable frequency drive? MV4 Series – A game-changing product Simple & efcient control of your process Appropriate power usage in response to load Variable frequency drives (VFDs) regulate motor speed to control the ow and pressure of blowers or pumps without dampers or throttling valves. This results in energy savings and no output waste. VFDs also provide a soft start to the motors, reducing the stress on driven load and resulting in lower maintenance costs. A VFD manages power based on actual demand and uses only the energy required by the driven equipment to provide valuable...

Process control benets MV4 Series drive options Critical speed avoidance One drive for multiple motors À la carte option packaging The MV4 Series drive provides six-cycle power loss ride-through and keeps the process running without tripping. The MV4 Series drive can be programmed for up to three critical frequency bands and ride-through these without any resonance issues. Under-voltage operation The MV4 Series operates continuously and provides available power to the motor at a lower input supply voltage (up to 70% of nominal voltage). Flying start into a spinning load The MV4 Series...
