OPTIMIZE MOTOR PERFORMANCE WITH RESPONSIBLE VFD MANAGEMENT PANELS FROM UAE

As an example, with a standard 480 VAC 3-phase enter voltage, the DC bus will hold a demand of about 650 VDC, with real bus voltage depending upon the line voltage level and motor load. The explanation the DC bus voltage is higher in comparison to the nominal input line voltage is a result of the root-indicate-squared measurements of AC sine waves
