LEARN UAE’S GREATEST VFD REGULATE PANELS FOR MOTOR VELOCITY REGULATION

As an example, with an average 480 VAC three-stage enter voltage, the DC bus will keep a charge of about 650 VDC, with genuine bus voltage dependant upon the line voltage degree and motor load. The main reason the DC bus voltage is bigger as opposed to nominal enter line voltage is due to root-imply-squared measurements of AC sine waves (the “pea
