AC/DC Current transducer DHR-C10
The transducer for the electronic measurement of DC & distorted AC
waveform currents, with galvanic isolation between the primary circuit
(power) and the secondary circuit (measurement). True RMS 0-10V
voltage output.

* The Max. Peak AC Current is the highest peak level of the primary signal that is
taken into account for accurate True RMS calculation. Yet the device is designed for
