DEPENDABLE VFD PANELS FOR MOTOR PACE MANAGE BY UAE’S PRIMARY SUPPLIERS

As an example, with a normal 480 VAC three-stage enter voltage, the DC bus will hold a cost of about 650 VDC, with genuine bus voltage dependant upon the line voltage degree and motor load. The rationale the DC bus voltage is higher than the nominal enter line voltage is due to the root-mean-squared measurements of AC sine waves (the “peaks” of
