| Product information | The ACT20P-CMT-XX-(AO)-RC-P series of devices measure and monitor AC and DC currents of up to 60 A. The real effective value method used allows for precise measurement, even for distorted current curve shapes. The devices feature integrated limit value monitoring with an adjustable switching threshold, delay and hysteresis, as well as a relay output.. Features Real effective value measurement (True RMS) or arithmetic averaging (AA) measurement and contactless through-hole technology Limit value monitoring for overcurrent or undercurrent Relay output by means of the open-circuit / closed-circuit principle Adjustable trigger delay for filtering current peaks Operational status and error display on a front panel LED and output signalling according to NE43, NE44, NE107 Galvanic four-way insulation for secure isolation according to IEC/EN 61010-2-201 |
