IMPROVE YOUR MOTOR EFFECTIVENESS WITH UAE’S PRIME VFD MANAGEMENT PANELS FOR INDUSTRIAL USE

As an example, with a typical 480 VAC three-stage enter voltage, the DC bus will hold a charge of about 650 VDC, with genuine bus voltage depending upon the line voltage amount and motor load. The key reason why the DC bus voltage is better as opposed to nominal enter line voltage is as a result of root-imply-squared measurements of AC sine waves (
