RELIABLE VFD MANAGEMENT PANELS FOR INDUSTRIAL PACE REGULATION IN UAE

For instance, with a standard 480 VAC 3-period enter voltage, the DC bus will maintain a cost of about 650 VDC, with precise bus voltage based on the line voltage stage and motor load. The reason the DC bus voltage is bigger than the nominal input line voltage is mainly because of the root-suggest-squared measurements of AC sine waves (the “peaks
