ENHANCE MOTOR PACE COMMAND WITH SUBSTANTIAL-EFFICIENCY VFD PANELS FROM UAE

For example, with a normal 480 VAC 3-stage enter voltage, the DC bus will hold a charge of about 650 VDC, with real bus voltage depending upon the line voltage level and motor load. The main reason the DC bus voltage is increased than the nominal enter line voltage is mainly because of the root-imply-squared measurements of AC sine waves (the “pe
