SUPERIOR VFD COMMAND PANELS FOR COST-PRODUCTIVE MOTOR SPEED CONTROL IN UAE

For instance, with a typical 480 VAC 3-period enter voltage, the DC bus will hold a charge of about 650 VDC, with genuine bus voltage with regards to the line voltage amount and motor load. The main reason the DC bus voltage is bigger as opposed to nominal input line voltage is a result of the root-signify-squared measurements of AC sine waves (the
