EL3443-0011 | EtherCAT Terminal, 3-channel analog input, power measurement, 480 V AC/DC, 0.1 A, 24 bit
The EL3443-0011 EtherCAT Terminal enables the measurement of all relevant electrical data of the supply network and carries out simple pre-evaluation. The voltage is measured via 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 root-mean-square values. In the EL3443-0011 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 EL3443-0011 offers extended functionality for mains analysis and energy management.
In addition, the EL3443-0011 comes with the option of transmitting the time of the last voltage zero crossing to the controller via XFC technology. This can be used, for example, to carry out switching operations to suit the application.
The 100 mA current interface is particularly well suited for active transformers and thus also for applications with high DC currents.
