EL3446-0011 | EtherCAT Terminal, 6-channel analog input, current, 0.1 A, 24 bit, distributed power measurement

The EL3446-0011 EtherCAT Terminal enables measurement of all relevant electrical data in the supply grid and performs simple pre-evaluations. Since the EL3446-0011 itself has no voltage inputs, the measured voltage values are transmitted via EtherCAT from an EL3443 to be installed once per network. The current in the connectable phases – of which there are up to six – is fed in via simple current transformers. All measured currents and voltages are available as RMS values. In the EL3446-0011, the active power and the energy consumption for each phase are calculated. RMS values are available for voltage U and current I as well as active power P, apparent power S, reactive power Q, frequency f, phase shift angle cos φ, and harmonics. The EL3446-0011 offers options for comprehensive network analysis and energy management.

With 100 mA inputs, the EL3446-0011 is particularly suitable for evaluating differential current transformers (such as the SCT4xxx) and DC-capable current transformers.
