EXPENSE-PRODUCTIVE VFD COMMAND PANELS FOR INDUSTRIAL MOTOR PACE MANAGE BY UAE PRODUCERS

For instance, with a typical 480 VAC 3-stage input voltage, the DC bus will keep a demand of about 650 VDC, with precise bus voltage with regards to the line voltage level and motor load. The rationale the DC bus voltage is increased compared to the nominal input line voltage is as a result of root-signify-squared measurements of AC sine waves (the
