Micro AC Variable Frequency Drives (VFD)

DURApulse and WEG micro variable frequency drives (VFD) enable speed control for 3-phase AC motors at an affordable price in a compact footprint. For applications with smaller motors, many micro drives support single-phase input power and some have high-end features such as vector control or a built-in PLC.
