SUPERIOR VFD PANELS FOR SUCCESSFUL ELECTRIC MOTOR REGULATE IN UAE

As an example, with a standard 480 VAC 3-section enter voltage, the DC bus will maintain a demand of about 650 VDC, with precise bus voltage with regards to the line voltage stage and motor load. The explanation the DC bus voltage is increased than the nominal enter line voltage is a result of the root-signify-squared measurements of AC sine waves
