The EL3423 EtherCAT Terminal enables the 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 Terminal, the effective power and the energy consumption for each phase are calculated. In addition, an internally calculated network quality factor provides information about the quality of the monitored voltage supply. The EL3423 offers basic functionality for mains analysis and energy management.
