^ BX units are different then the bxri units, possibly an interior modification that has been corrected with newer models. I had older elinchrom el 500's and tried it with the smart ups. If i connected 3 el500's, the ups would overload and trip the reset switch in the back.
d-lite 4's however did not trip the reset switch.
My chart results are pretty accurate with the amount of pops you'd expect to get out of a flash. plan accordingly. hard numbers give better facts then general flash amounts. i'll be doing that test with the minivag when i get mine.
