HIGH QUALITY VFD PANELS FOR ELECTRICAL POWER-SAVING MOTOR PACE REGULATE IN UAE

For example, with an average 480 VAC 3-section input voltage, the DC bus will maintain a charge of about 650 VDC, with real bus voltage according to the line voltage stage and motor load. The reason the DC bus voltage is increased compared to nominal enter line voltage is as a result of root-suggest-squared measurements of AC sine waves (the “pea
