1.3. THREE-PHASE AMPFLEX
®
The AmpFlex
®
series A130 sensor converts alternating currents ranging from 30 to 3000 A into proportional
AC voltages. It comprises 3 sensors 80 cm long connected to the electronic unit. The output is via 3
BNC connectors on which it is possible to place the adapters provided in order to obtain outputs with 2
safety plugs.
The three outputs of the electronic unit can be connected to a standard wattmeter (as auxiliary inputs),
to multimeters, to a recorder, etc.

3 BNC
connectors, each
corresponding to
a sensor.
The multimeter or instrument connected must have a maximum voltage and a measurement
category at least equal to those of the AmpFlex
®
sensor, since otherwise the maximum voltage
and category of the assembly will be those of the lowest‑rated component.
