EXCEPTIONAL VFD PANELS FOR VALUE-PRODUCTIVE MOTOR VELOCITY MANAGE IN UAE

For example, with an average 480 VAC 3-phase enter voltage, the DC bus will hold a cost of about 650 VDC, with genuine bus voltage depending upon the line voltage degree and motor load. The key reason why the DC bus voltage is greater compared to nominal enter line voltage is mainly because of the root-suggest-squared measurements of AC sine waves
