REPUTABLE VFD PANELS FOR MOTOR PACE OPTIMIZATION IN UAE PROGRAMS

For instance, with a typical 480 VAC 3-section input voltage, the DC bus will keep a charge of about 650 VDC, with genuine bus voltage depending on the line voltage degree and motor load. The rationale the DC bus voltage is greater than the nominal enter line voltage is because of the root-necessarily mean-squared measurements of AC sine waves (the
