ENHANCE ELECTRICAL MOTOR SPEED WITH PRIME VFD PANELS FROM UAE

For example, with an average 480 VAC three-phase input voltage, the DC bus will keep a charge of about 650 VDC, with true bus voltage based on the line voltage amount and motor load. The reason the DC bus voltage is higher compared to nominal enter line voltage is as a result of root-signify-squared measurements of AC sine waves (the “peaks” of
