Superior VFD Command Panels for Optimizing Electric powered Motor Velocity in UAE
For instance, with a standard 480 VAC 3-stage input voltage, the DC bus will hold a demand of about 650 VDC, with precise bus voltage dependant upon the line voltage level and motor load. The main reason the DC bus voltage is better than the nominal input line voltage is due to the root-suggest-squared measurements of AC sine waves (the “peaks”
