EL3446 - Introduction
EL3446 | 6-channel current input terminal 1 A AC/DC for distributed power measurement
Fig.10: EL3446The EL3446 EtherCAT Terminal enables the measurement of all relevant electrical data of the supply network and carries out simple pre-evaluation.
Since the EL3446 itself has no voltage inputs, the voltage measured values are transmitted via EtherCAT by an EL3443 to be installed once per network. The current of the up to six connectable phases is fed in via simple current transformers (e.g. the Beckhoff SCT series).
All measured currents and voltages are available as RMS values. In the EL3446 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 EL3446 offers extended functionality for mains analysis and energy management.
