HIGHER-PERFORMANCE VFD PANELS FOR MOTOR VELOCITY REGULATION BY UAE AUTHORITIES

For example, with a standard 480 VAC three-period enter voltage, the DC bus will keep a charge of about 650 VDC, with real bus voltage depending upon the line voltage amount and motor load. The reason the DC bus voltage is greater compared to the nominal input line voltage is due to root-indicate-squared measurements of AC sine waves (the “peaks�
