Chauvin Arnoux AmpFlex A110-45 [P01120630] 3000 A Flexible Current Clamp

The AmpFlex® A110 is a fl exible sensor which comprises an active part (Rogowski coil) and a casing containing an electronic processing unit. Unlike current clamps using magnetic circuits, the AmpFlex® models are fl exible sensors without magnetic saturation constraints. As a result, they offer excellent linearity, low phase shift, a large dynamic range for measurement (up to several kA) while remaining easy to use. The sensors’ fl exibility makes it easy to clamp the conductor, whatever its type (cable, busbar, strand, etc.) and access conditions.

The design of the click-together opening and closing system means it can be handled with protective gloves. The AmpFlex® A110 can be connected to the AC voltage input (mV AC, V AC) of any multimeter or measuring instrument equipped with Ø 4 mm female banana plugs. The AmpFlex® A110 can be powered by batteries or a standard external power supply. If the power supply fails, the instrument’s batteries take over. To maximize the battery life, the MiniFlex® A110 has an automatic standby system which can be deactivated at start-up to perform long-term measurement campaigns.

The MiniFlex® A110 has 3 green, yellow and red LEDs indicating, respectively, the power supply status, the status of the automatic standby function and any overruns of the measurement capacity.
