TOP QUALITY VFD PANELS FOR INCREASED ELECTRICAL MOTOR SPEED REGULATION IN UAE

As an example, with a typical 480 VAC three-stage enter voltage, the DC bus will keep a cost of about 650 VDC, with actual bus voltage according to the line voltage level and motor load. The main reason the DC bus voltage is bigger when compared to the nominal input line voltage is due to the root-signify-squared measurements of AC sine waves (the
