The HAZ Series of high current DC current transducers (CTs) from LEM covers the 4000–20 000 A current measurement range. The transducers use open loop Hall effect measurement techniques and provide galvanic isolation of up to 12 kV between the primary and secondary circuit. The compact and easy to mount CTs are designed to accommodate busbars of up to 152 x 42 mm.
A wide range of outputs are available including instantaneous bipolar ±10 V, ±20 mA, unipolar true rms +10 V, +20 mA and 4–20 mA.
This series of CTs is suited for use in battery supplied applications, traction, UPS, power supplies for welding, telecommunications as well as electro-chemical processes.
