| Product information | The ACT20C-CMT-XX-AO-RC-S current measuring transducers from the ACT20C series measure and monitor DC and AC currents of up to 60 A. The True RMS method used allows for precise measurement, even in case of distorted current waveforms. The devices feature integrated limit value monitoring with an adjustable switching threshold, delay and hysteresis, as well as a relay output. Properties True RMS value measurement or arithmetic averaging (AA) measurement and contactless through-hole technologyLimit value monitoring for overcurrent or undercurrentRelay output by means of the open-circuit / closed-circuit principleInfinitely variable trigger delayOperational status and error display on a front panel LED and output signalling according to NE43, NE44, NE107Galvanic four-way insulation for secure isolation according to IEC/EN 61010-2-201:2013 |
