Description

ACS380-040S-038A-4 A variable frequency drive, also called a frequency inverter, adjustable speed drive, the basic working principle is to adjust the electrical supply of an AC motor to a consistent frequency and voltage change at the motor speed and torque output. The most common use of a VFD is for fan, pump, and compressor control, and these applications account for 75% of all drives operated worldwide.
