3.1 EL34xx – Introduction
EL3443 | 3-phase power measurement terminal with extended functionality
Fig.10: EL3443
The 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 via simple current transformers.
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 active power P, apparent power S, reactive power Q, frequency f, phase shift angle cos φ and
harmonics are available. The EL3443 offers options for comprehensive grid analysis and energy
management.
Variants:
• EL3443-0000: Version with direct current measurement up to 1 A
• EL3443-0010: Version with direct current measurement up to 5 A
• EL3443-0011: Version with direct current measurement 100 mA
• EL3443-0013: Version with direct voltage measurement 333 mV
