3-phase power measurement terminal, 500 V AC, 10 A
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. Hence, 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 network analysis up to the 21
st
harmonic analysis. Like all measured
terminal data, the harmonic content can be read via the process data.
