The Chauvin Arnoux Amp flex A130 is a flexible current sensor comprising 3 measurement loops. It can be connected directly to a power analyser, logger, etc., to measure 3-phase currents or to perform up to 3 independent current measurements. Their flexible, lightweight design means they can encircle one or more conductors, whatever their shape (cable, busbar, strand, etc.). It's Bandwidth is suitable for industrial frequencies and harmonic analysis.

It has Large measurement range of 0.5 A to 3 kA
It has no saturation effect, so no overheating
It has constant low phase shift appropriate for watt metric measurements
Output via 3 coaxial cables terminated by isolated BNC safety plugs
It has a battery life up to 500 hours
