EL3433 EtherCAT Terminal

The EL3433 is a three-phase power measurement terminal from the Beckhoff EtherCAT Terminal series, designed for direct measurement of electrical power in three-phase AC systems. It measures voltage and current on all three phases and calculates RMS values, active/reactive/apparent power, power factor, frequency, and energy, delivering the results to the controller over EtherCAT. It is a high-feature member of the EL34xx power measurement family; the exact feature differences versus the EL3403 and EL3413 should be confirmed in the current Beckhoff datasheet.
