High quality VFD Panels for Improved Electric powered Motor Pace Regulation in UAE
For example, with a typical 480 VAC three-phase enter voltage, the DC bus will keep a charge of about 650 VDC, with real bus voltage with regards to the line voltage level and motor load. The main reason the DC bus voltage is greater as opposed to nominal input line voltage is due to root-indicate-squared measurements of AC sine waves (the “peaks
