100-120 VAC INPUT Variable frequency drives

100-120 VAC vfd's are designed to support the same volt power supply which means 100-120 volt power supply. The compatibility of the variable frequency drive with the motor as well as the power for which it is being installed should be good. A less power supply supporting vfd will not be able to handle 100-120 volt. It should be of the same voltage or higher than that.
