STATE-OF-THE-ART VFD PANELS FOR PRICE TAG-EFFICIENT MOTOR SPEED OPTIMIZATION BY UAE COMPANIES

For instance, with a typical 480 VAC 3-stage enter voltage, the DC bus will hold a demand of about 650 VDC, with true bus voltage with regards to the line voltage degree and motor load. The reason the DC bus voltage is better when compared to the nominal input line voltage is mainly because of the root-indicate-squared measurements of AC sine waves
