PRIME VFD PANELS FOR COST-POWERFUL VELOCITY REGULATION IN UAE INDUSTRIES

For example, with an average 480 VAC three-section enter voltage, the DC bus will keep a cost of about 650 VDC, with actual bus voltage depending on the line voltage degree and motor load. The reason the DC bus voltage is higher than the nominal enter line voltage is mainly because of the root-suggest-squared measurements of AC sine waves (the “p
