LEARN TAILOR MADE VFD REGULATE PANELS FOR PRECISE MOTOR SPEED OPTIMIZATION IN UAE

As an example, with a typical 480 VAC 3-period enter voltage, the DC bus will keep a demand of about 650 VDC, with true bus voltage depending on the line voltage stage and motor load. The reason the DC bus voltage is increased than the nominal input line voltage is mainly because of the root-indicate-squared measurements of AC sine waves (the “pe
