ENRICH ELECTRIC MOTOR EFFECTIVENESS WITH RELIABLE VFD PANELS FROM UAE

For instance, with a typical 480 VAC 3-section enter voltage, the DC bus will hold a charge of about 650 VDC, with true bus voltage based on the line voltage degree and motor load. The rationale the DC bus voltage is higher as opposed to nominal input line voltage is due to root-mean-squared measurements of AC sine waves (the “peaks” of the 480
