FIND OUT CHARGE-EFFECTIVE VFD PANELS FOR INDUSTRIAL MOTOR OPTIMIZATION

As an example, with a typical 480 VAC three-stage enter voltage, the DC bus will keep a demand of about 650 VDC, with genuine bus voltage depending on the line voltage level and motor load. The rationale the DC bus voltage is greater in comparison to the nominal input line voltage is due to the root-mean-squared measurements of AC sine waves (the â
