A303 phase detector

Based on amperometric detection, this device is not affected by motor-generated back Emf voltage nor by the network''s supply frequency.
The device uses its two internal transducers to check if the three currents of a three-phase system exist and what is their sequence
By checking two of the three currents in a three-phase system, the model S can detect the phase sequence (L12, L2, L3 or L1, L3, L2) or the absence of the these currents (single-phase mode)
