UNCOVER UAE’S FOREMOST VFD CONTROL PANELS FOR INDUSTRIAL MOTOR OPTIMIZATION

As an example, with an average 480 VAC 3-phase input voltage, the DC bus will keep a demand of about 650 VDC, with real bus voltage according to the line voltage amount and motor load. The reason the DC bus voltage is larger as opposed to nominal input line voltage is a result of the root-indicate-squared measurements of AC sine waves (the “peaks
