The DHR-C10 AC/DC current transducer is a high-precision, low-power, small-sized, large-output current sensor. It adopts the Hall effect principle, and uses the iron oxide magnetic core and the bipolar transistor magnetic coupling to convert the large current signal to a low-current signal that can be used for measurement and control systems.
The LEM DHR‑C10 is an AC/DC current transducer designed for electronic measurement of DC and distorted AC waveforms, offering galvanic isolation between the high‑power primary and the low‑power secondary circuits.
It supports a primary current range of 100‑1000 A, delivers a true‑RMS 0‑10 V output, operates from a +20‑50 VDC supply, and meets high accuracy (<0.1 % of reading) and linearity (<1 %). The device is rated for 1000 V isolation, IP20 protection, and features compact panel‑mount dimensions.
