HIGH-OVERALL PERFORMANCE VFD HANDLE PANELS FOR POWER-SUCCESSFUL SPEED REGULATION IN UAE

As an example, with an average 480 VAC 3-section input voltage, the DC bus will keep a charge of about 650 VDC, with genuine bus voltage with regards to the line voltage amount and motor load. The rationale the DC bus voltage is higher compared to nominal enter line voltage is because of the root-suggest-squared measurements of AC sine waves (the �
