WM4-96 PHILOSOPHY (IMPORTANT)

WM4-96 is able to meet all the requirements in the

field of energy management and of power quality analysis.
WM4-96 can work, according to the needs, in three differ-
ent operating modes, obtained by means of hardware and
software configurations.

-

direct measurements for monitoring the network quality
and energy metering (LV or MT/HV connection).
