INNOVATIVE VFD PANELS FOR PRICE TAG-POWERFUL MOTOR PACE REGULATION IN UAE

For example, with a normal 480 VAC 3-period input voltage, the DC bus will maintain a cost of about 650 VDC, with precise bus voltage depending upon the line voltage level and motor load. The explanation the DC bus voltage is larger than the nominal enter line voltage is mainly because of the root-suggest-squared measurements of AC sine waves (the
