Responsible VFD Panels for Industrial Motor Pace Manage by Main UAE Suppliers
As an example, with a typical 480 VAC 3-section enter voltage, the DC bus will keep a charge of about 650 VDC, with actual bus voltage according to the line voltage stage and motor load. The reason the DC bus voltage is increased when compared to the nominal input line voltage is due to the root-indicate-squared measurements of AC sine waves (the �
