GREATLY ENHANCE MOTOR EFFICIENCY WITH EXPENSE-PRODUCTIVE VFD PANELS FROM UAE

For instance, with a normal 480 VAC three-phase input voltage, the DC bus will maintain a cost of about 650 VDC, with precise bus voltage depending on the line voltage degree and motor load. The reason the DC bus voltage is larger than the nominal enter line voltage is a result of the root-necessarily mean-squared measurements of AC sine waves (the
