ENHANCE ELECTRIC MOTOR OVERALL PERFORMANCE WITH TOP VFD PANELS FROM UAE BRANDS

For example, with a standard 480 VAC 3-period enter voltage, the DC bus will keep a charge of about 650 VDC, with precise bus voltage depending on the line voltage stage and motor load. The reason the DC bus voltage is bigger compared to the nominal input line voltage is mainly because of the root-imply-squared measurements of AC sine waves (the â€
