Beckhoff EL3433 is a 3-phase power measurement terminal for EtherCAT with internal current transformers, measuring currents up to 10 A AC directly (I1, I2, I3 and In) and voltages up to 500 V AC 3~ (288 V AC phase to neutral). It provides voltage, effective, reactive and apparent power, energy, cos φ, frequency and harmonic analysis up to the 21st harmonic, with a resolution of 1 µA, 0.1 mV and 10 mW and a measurement error of 0.5 % of full scale (U/I) and 1 % for calculated values. It has 4500 V electrical isolation, draws typically 200 mA from the E-bus and is rated IP20 for -25 to +60 °C; Beckhoff lists it as a service-phase product.
