RELIABLE VFD PANELS FOR MOTOR SPEED OPTIMIZATION IN UAE

As an example, with a normal 480 VAC 3-section enter voltage, the DC bus will hold a demand of about 650 VDC, with true bus voltage dependant upon the line voltage amount and motor load. The reason the DC bus voltage is better than the nominal input line voltage is mainly because of the root-signify-squared measurements of AC sine waves (the “pea
