SOPHISTICATED VFD PANELS FOR SUCCESSFUL ELECTRIC POWERED MOTOR VELOCITY CONTROL IN UAE

As an example, with a typical 480 VAC 3-section input voltage, the DC bus will keep a demand of about 650 VDC, with true bus voltage depending upon the line voltage level and motor load. The rationale the DC bus voltage is greater in comparison to the nominal enter line voltage is due to the root-mean-squared measurements of AC sine waves (the “p
