TOP QUALITY VFD HANDLE PANELS FOR EFFECTIVE INDUSTRIAL MOTOR SPEED REGULATION

For example, with a typical 480 VAC 3-phase input voltage, the DC bus will maintain a charge of about 650 VDC, with true bus voltage depending on the line voltage level and motor load. The reason the DC bus voltage is greater when compared to the nominal input line voltage is due to root-suggest-squared measurements of AC sine waves (the “peaks�
