Invt AC Drives are the controlling units that are used to alter the frequency of the electrical signals coming from the main supply and then feed it to the high speed motors to increase or decrease the speed of the rotor. These devices functions by converting the voltage from AC to DC and then again to AC as well as adjusting the frequency values. Invt AC Drives are available in various different variants with a current capacity in between 100 to 200 ampere. They are designed for process controlling and are equipped with components which consumes very less power.
