EL3444 – Introduction
EL3444 | 4-channel current analog input terminal 10 A AC/DC for distributed power measurement, electrically isolated
Fig.8: EL3444The 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 the up to four lockable, electrically isolated phases is fed in directly. All measured currents and voltages are available as RMS values. In the EL3444 version, the active power and the energy consumption for each phase are calculated.
The RMS values of 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 are available. The EL3444 offers extended functionality for mains analysis and energy management.
