OVERVIEW
The R734 optional three phase sensing module is designed to be used with the R 438, R 448, R 449, R452 single phase sensing voltage regulators. The module R 734 has an additional function compared to module R 731 : it has a 3 phase current sensing/ quadrature droop which enables it paralleling with highly unbalanced loads (i.e. mainly consisting in single phase loads connected line to neutral).
