HIGHER-HIGH QUALITY VFD PANELS FOR PRECISE MOTOR VELOCITY COMMAND IN UAE

For instance, with a typical 480 VAC three-section enter voltage, the DC bus will hold a charge of about 650 VDC, with true bus voltage depending on the line voltage amount and motor load. The main reason the DC bus voltage is greater compared to nominal enter line voltage is due to root-imply-squared measurements of AC sine waves (the “peaks”
