Multirange c.t. With 4-20ma output series MAC…/MAT…

Multirange current transformers, with loop-powered 4…20mA output (also called “pas-sive”), are innovative products which permit to get a current measurement directly on a PLC or an acquisition system, without interposition of separated transducers and without auxiliary power connections. The electronic circuits, to transduce the measure and to generate the output signal, are actually integrated in the transformer housing, together with a miniature switch used to select one of the available ranges , and are powered with the same wires of the output. This means a great costs reduction, a very simple wiring and a generally improved relia-bility..

In case it is necessary to measure currents with distorted waveforms, it is optionally available the version with TRMS measurement (add an “R” before the “G” in the ordering code).

A.C. CURRENT TRANSDUCERS WITH INTEGRATED C.T.

These transducers, with integrated current transformer, are suitable to measure the rms value of currents with sinusoidal undistorted waveforms or, for the TRMS types only, also with distorted waveforms; in this case the additional error is 0.5% for crest factor < 3 and 1% for crest factor < 7. The outputs are load independent d.c. current or voltage, propor-tional to the input variable.
