Variable-Frequency AC Drives

The VariFlex Series of ac drives handle general-purpose three-phase motor-control applications

from 1 /3 to 5 hp. The front cover of the variable-frequency drive lists the 10 most commonly used drive parameters. Available frame sizes A, B, and C cover main voltages from 180 to 528 Vac, and they accept both single and three-phase supply voltages. The VariFlex Series has standard Modbus capabilities as well as a compact SmartStick that quickly clones the programming from one drive to others.
