OUTSTANDING VFD MANAGEMENT PANELS FOR OPTIMIZING MOTOR PACE IN UAE INDUSTRIES

For example, with a normal 480 VAC 3-stage input voltage, the DC bus will hold a charge of about 650 VDC, with actual bus voltage dependant upon the line voltage level and motor load. The reason the DC bus voltage is better as opposed to nominal input line voltage is due to the root-signify-squared measurements of AC sine waves (the “peaks” of
