Closed-loop current sensor A130

clampthree-phase

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 Main specifications : • Measurement range: 0.5 A to 3 kA • 3 calibres • Sensor length (clamping Ø): 80 cm (Ø25 cm) • Ingress protection of sensor/processing unit: IP67 / IP54 • Output signal: AC voltage • Output via 3 coaxial cables terminated by isolated BNC safety plugs • Power supply: 2 x 1.5V AA batteries or external µUSB type B 5V • Battery life: 500 hours • 1,000 V CAT IV
