EL3483 - Introduction
EL3483 | 3-phase mains monitoring terminal for voltage, frequency and phase
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 grid analysis and mains control. The EL3483-0060 version also outputs the current rms values of the voltage in the process image.
