Product Description
3-phase compact power
transducer. Particularly rec-
ommended for the measure-
ment of the main electrical
variables also on board of
machines.
Housing for DIN-rail mount-
ing, with up to 3 analogue
outputs, or RS485 communi-
cation port or alarm outputs
or “Dupline” bus. Parameters
programmable by means of
CptASoft.
