Current transducers HAZ 4000..20000-SRI are for the electronic measurement of currents: DC, AC, pulsed, mixed, with a galvanic isolation between the primary circuit (high power) and the secondary.
The document describes the LEM HAZ 4000..20000-SRI Current Transducers, designed for measuring DC, AC, pulsed, and mixed currents with galvanic isolation between high-power primary circuits and electronic secondary circuits. The devices utilize a Hall effect measuring principle to provide a true-rms, 0-20mA DC current output.
