Dear All
can any one told me that VFD Make ABB Model ACS800-01 used for dual Source like
1.DC Source applied at terminal UDC+,UDC-
2. 3 phase 400AC,50Hz
Answer / alf
Poorly worded question.
1) The VSD (Inverter) is connected to an external supply at 400V, 3ph, 50Hz..
2) UDC+, UDC- (R+; R-) are the terminals for connecting an external brake. The voltage on these terminals is over 500Vdc and is supplied FROM the VSD, not connetected TO the VSD
