Presentation; General; Single-Phase Ampflex - Chauvin Arnoux AmpFlex A110 Notice De Fonctionnement

1.1. GENERAL

AmpFlex sensors take the form of a flexible coil connected by a shielded lead to a housing containing
®
the signal processing electronics, powered by batteries.
The flexibility of the sensors facilitates the clamping of the conductor to be measured, whatever its nature
(cable, bar, strand, etc.) and its accessibility. The design of the coil opening and closing device, by snap
locking, allows handling while wearing protective gloves.
The electronic unit can be connected to the mV
impedance of ≥ 1 MW.

1.2. SINGLE-PHASE AMPFLEX

AmpFlex series A110 single‑phase sensors constitute a line of three models, 45, 80, and 120 cm long,
®
that convert alternating currents ranging from 3 to 3000 A (for the 45 and 80 cm models) or from 30 to
30,000 A (for the 120 cm model) into proportional AC voltages.
