SCT5564 Ring-type CT and EL3444 power measurement terminal

The EL3444 EtherCAT Terminal enables the measurement of all relevant electrical data of the supply network and carries out simple pre-evaluation. Since the EL3444 itself has no voltage inputs, the voltage measured values are transmitted via EtherCAT by an EL3453 to be installed once per network. The current of up to six galvanically isolated phases is fed in directly. All measured currents and voltages are available as root-mean-square values. In the EL3444 terminal, the effective power and energy consumption for each phase are calculated. The RMS values of voltage U and current I as well as the active power P, apparent power S, reactive power Q, frequency f, phase shift angle cos φ and harmonic are available. The EL3444 offers extended functionality for mains analysis and energy management.
