Product overview
EL34x3 17 Version: 4.4

3-Phase Power Measurement Terminal
The EL3413 EtherCAT power measurement terminal is a further development of the EL3403. With up to
690 V AC the voltage inputs are optimized for direct monitoring of high-performance generators, as used in
the wind power industry, for sample.
The full scale value for the current can be set to 0.1 A, 1 A or 5 A via the CoE directory.
No upstream voltage transformer is required. The current inputs are electrically isolated so that the terminal
can be used in all common grounded current transformer configurations such as 2- or 3-transformer
configurations with star or delta connection.
Like all measured terminal data, the harmonic content can be read via the process data.
The EL3413-0001 has a maximum input voltage of 600 V AC and is additionally UL-certified.
In the case of the EL3413-0120 the voltage range is limited to 210 V AC.
