Reputable VFD Command Panels for Efficient Speed Control in UAE Industries
For example, with an average 480 VAC three-stage enter voltage, the DC bus will hold a charge of about 650 VDC, with actual bus voltage depending on the line voltage stage and motor load. The explanation the DC bus voltage is bigger compared to the nominal enter line voltage is as a result of root-imply-squared measurements of AC sine waves (the �
