EXCEPTIONAL VFD PANELS FOR ENHANCING INDUSTRIAL MOTOR EFFICIENCY IN UAE

For example, with a normal 480 VAC three-section enter voltage, the DC bus will hold a charge of about 650 VDC, with true bus voltage according to the line voltage degree and motor load. The rationale the DC bus voltage is higher as opposed to nominal enter line voltage is as a result of root-signify-squared measurements of AC sine waves (the “pe
