IMPROVE ELECTRIC MOTOR SPEED WITH UAE’S LEADING VFD CONTROL PANELS

As an example, with a typical 480 VAC 3-section input voltage, the DC bus will hold a charge of about 650 VDC, with precise bus voltage according to the line voltage level and motor load. The reason the DC bus voltage is higher in comparison to the nominal enter line voltage is as a result of root-indicate-squared measurements of AC sine waves (the
