LEM, DHR Series, CURRENT TRANSDUCER, 100 AMP

PART MODEL: DHR 100 C420

Industrial-grade, high-performance, open-loop Hall Effect current transducer manufactured by LEM. Engineered for the highly accurate, non-contact measurement of DC, AC, pulsed, and complex distorted electrical waveforms, this device features built-in signal conditioning that outputs a industry-standard True RMS 4-20 mA analog DC loop signal.

Designed with a generous 32 mm circular primary aperture, the transducer easily accommodates heavy-duty power cables and busbars without needing to physically cut or interrupt the primary circuit. This completely eliminates insertion loss while providing robust galvanic isolation (up to 4.0 kV) between the high-power primary line and sensitive secondary automation controllers (such as PLCs, RTUs, or telemetry modules). Thanks to its integrated True RMS calculation engine, it is exceptional at accurately monitoring distorted waveforms produced VFDs and SCRs.
