Product overview
EL3423 | 3-phase power measurement terminal, Economy
Fig. 11: EL3423
The EL3423 EtherCAT Terminal enables measurement of relevant data for an efficient energy management
system. The voltage is measured internally via direct connection of L1, L2, L3 and N. The current of the three
phases L1, L2 and L3 is fed via simple current transformers. The measured energy values are available
separately as generated and accepted values. In the EL3423 version, the active power and the energy
consumption for each phase are calculated. In addition, an internally calculated power quality factor provides
information about the quality of the monitored power supply. The EL3423 offers basic functionality for mains
analysis and energy management.
