SUPERIOR VFD CONTROL PANELS FOR IMPROVED MOTOR SPEED REGULATE BY UAE SUPPLIERS

As an example, with a typical 480 VAC 3-period input voltage, the DC bus will maintain a charge of about 650 VDC, with genuine bus voltage based on the line voltage level and motor load. The explanation the DC bus voltage is greater as opposed to nominal input line voltage is due to the root-imply-squared measurements of AC sine waves (the “peaks
