(some units)
Using single-phase drive to operate a three phase motor raises the efficiency as on fans or pumps
Changes the motor speed smoothly making the best of your flow to save you money such as on Food Processing Machines
Speed control can be accomplished using only digital inputs to select up to 10 preset speeds
This drive can operate on either 50 or 60 HZ power and can convert 50 HZ power to 60 HZ output or 60HZ power to 50 HZ output
