The EL3433 EtherCAT power measurement terminal is a further development of the EL3403. Currents of up to 10 A can be directly measured with the internal current transformers. This way, there are no additional costs for external current transformers. The external bridges 5 & 1', 6 & 2' and 7 & 3' are already pre-wired. As a result, it is possible to directly connect the supply voltage (5', 6' and 7') and the consumer (1, 2 and 3). The EL3433 can deal with simple grid analysis up to the 21st harmonic analysis. Like all measured terminal data, the harmonic content can be read via the process data.
The EL3433 power measurement terminal has neutral conductor current measurement as standard since the 3rd quarter of 2015. At no additional cost to the end user, the terminal features a shunt between pin 4 and pin 8, in order to enable direct neutral conductor analysis.
