AHR Series

Compact and versatile split core transducers for high AC and DC currents from 500 to 2000A.

AHR - Split Core Transducers

The AHR Series is designed for the electronic measurement of currents: DC, AC, pulsed... It comes up with galvanic separation and high insulation between the primary circuit and the secondary circuit.

One of AHR mains advantages comes from it ability to eliminate insertion losses. It is also easy to install.
