EL3483 | 3-phase mains monitoring terminal for voltage, frequency and phase
Fig.12: EL3483
The EL3483 EtherCAT Terminal enables monitoring of relevant electrical data of the supply network. The
voltage is measured internally via direct connection of L1, L2, L3 and N. The internal measured values are
compared with threshold values preset by the user. The result is available as digital information in the
process image.
The EL3483 monitors the correct phase sequence L1, L2, L3, phase failure, undervoltage and overvoltage
and possible phase imbalance. An error bit is set in case of an incorrect phase sequence or phase failure. If,
for example, an imbalance or voltage fault occurs, only a warning bit is set initially. In addition, an internally
calculated power quality factor provides information about the quality of the monitored power supply. The
EL3483 offers options for simple mains analysis and network control.
The EL3483-0060 variant also outputs the current effective voltage values in the process image.
