EL3443 - Introduction
EL3443 | 3-phase power measurement terminal with extended functionality
Fig.6: EL3443The EL3443 EtherCAT Terminal enables measurement of all relevant electrical data of the mains supply and performs simple pre-evaluations. The voltage is measured via the direct connection of L1, L2, L3 and N. The current of the three phases L1, L2 and L3 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 EL3443 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 the active power P, apparent power S, reactive power Q, frequency f, power factor PF and cos φ beside phase shift angle and harmonic are available.
The EL3443 offers options for comprehensive grid analysis and energy management.
