IEC 61557-12 PMD/DD/K55/1 PowerTags are energy sensor modules for 1P, 1P+N, 3P and 3P+N networks. They are mounted directly on equipment of the Acti 9 or Multi 9 range at intervals of 18 mm up to 63 A.
Functions Combined with Acti 9 Smartlink SI B (Ethernet) or Acti 9 Smartlink SI D (Ethernet) by radio-frequency communication, PowerTag sensors measure the following values in accordance with the IEC 61557-12 standard b Cumulative active energy, total and partial (kWh). b Rms values: v phase-to-neutral and phase-to-phase voltages (V), v currents per phase (A), v total active power and active power per phase (W), v power factor. Installed upstream or downstream of a protective device, they measure useful data for diagnosis of the associated circuit. b Class 1 measurement accuracy of energy and current, and class 0.5 of voltage.
