STATE-OF-THE-ART VFD PANELS FOR ELECTRICAL POWER-EFFICIENT SPEED CONTROL BY UAE SUPPLIERS

For example, with an average 480 VAC 3-stage enter voltage, the DC bus will hold a charge of about 650 VDC, with genuine bus voltage according to the line voltage stage and motor load. The main reason the DC bus voltage is better compared to nominal enter line voltage is due to the root-indicate-squared measurements of AC sine waves (the “peaksâ€
