The AmpFlex® 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.
These flexible cores offer the following major advantages:

• Their flexible, lightweight design means they can encircle one or more conductors, whatever their shape (cable, busbar, strand, etc.)
• Large measurement range
• Bandwidth suitable for industrial frequencies and harmonic analysis
• No saturation effect, so no overheating
• Constant low phase shift appropriate for wattmetric measurements
