| Description de l'article | Operating and residual current monitoring device / supply voltage 230V AC, 768 KB memory, 20 current measurement channels, MODBUS, DIN rail mounting (6 te) / continuous acquisition of the operating currents and permanent residual current monitoring for permanent monitoring and logging of processes in TN-s or TN-c-s systems. 20 current measurement channels +/- 0.5 %, 3 voltage measurement channels +/- 0.5 %, internal RS485 interface (MODBUS as slave), measurement range of operation current with burden up to 63 A with closed or split core current transformers. Standard measured values: V, a, KW, KVA, KVAR, KWH. Polarity reversal for the current channels, memory function for the messages of the threshold monitoring, integration in the GRIDVIS® software, diverse current transformer variants for the individual application. Measurement variants: Three-phase and single-phase energy measurement |
