HY – Current sensors for the industrial sector
The HY Series is designed for the electronic measurement of DC, AC, and pulsed currents, providing galvanic isolation between the primary and secondary circuits. These current transducers offer a variety of measurement ranges within the same housing, from ±15 A to ±150 A.
HY sensors come with several competitive advantages, including a compact size, dual supply voltage of ±12V to ±15V, and voltage output. They can measure up to three times the nominal current (3 x Ipn) and are intended for PCB mounting.
Utilizing open-loop Hall effect technology, HY transducers are ideal for industrial applications.
