EL3423 - Introduction
EL3423 | 3-phase power measurement terminal, Economy
Fig.4: EL3423The 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 in via simple current transformers (e.g. the Beckhoff SCT series). The measured energy values are available separately as generated and delivered 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 grid analysis and energy management.
