Three-Phase Miniflex - Chauvin Arnoux MiniFlex MA110 Manual De Instrucciones

1.3. THREE-PHASE MINIFLEX

The MiniFlex series MA130 sensor converts alternating currents ranging from 30 to 3000 A into
®
proportional AC voltages. It comprises 3 sensors 25 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 current sensors for 3
phases.
The multimeter or instrument connected must have a maximum voltage and a measurement
category at least equal to those of the MiniFlex
and category of the assembly will be those of the lowest‑rated component.
