SUPERIOR VFD MANAGEMENT PANELS FOR VALUE-POWERFUL MOTOR PACE OPTIMIZATION IN UAE

For example, with a normal 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 amount and motor load. The explanation the DC bus voltage is larger than the nominal input line voltage is due to root-indicate-squared measurements of AC sine waves (the “peaks” of
