PRIME VFD MANAGEMENT PANELS FOR EXACT MOTOR SPEED REGULATION IN UAE

As an example, with a standard 480 VAC three-phase input voltage, the DC bus will hold a cost of about 650 VDC, with true bus voltage based on the line voltage level and motor load. The key reason why the DC bus voltage is larger when compared to the nominal enter line voltage is due to root-mean-squared measurements of AC sine waves (the “peaks�
