MDC-DR-10S-A

Dual Range Current Sensor

A dual-range current Sensor for safety-critical applications, offering two independent analog outputs. Thanks to the non-intrusive clamp-on design, the sensor can be easily installed without disconnection, making it ideal for retrofit installations in industrial, IoT, and metering applications. Furthermore, a broad dynamic range of currents can be measured and the customer requires no calibration.

Series Resources

Current Sensing for High Power

When powered with a DC voltage of 5V or 10V, the module delivers a linear analog output ranging from 0.5V to 4.5V or 1V to 9V, corresponding to the primary input current. This sensor boasts exceptional linearity, with an error margin of less than 0.5% FS.

Equipped with a Melexis IMC-Hall® current sensor, the module offers outstanding offset stability, as low as ±5mV, and maintains sensitivity drift to just 1% across the full temperature range. The module features a dual-range output, with each Hall sensor generating a signal tailored to the maximum current range.
