OPTIMIZE MOTOR EFFECTIVENESS WITH RELIABLE VFD MANAGEMENT PANELS FROM UAE

For example, with a normal 480 VAC three-section enter voltage, the DC bus will hold a charge of about 650 VDC, with true bus voltage dependant upon the line voltage level and motor load. The rationale the DC bus voltage is increased compared to nominal enter line voltage is because of the root-indicate-squared measurements of AC sine waves (the �
