3-Phase Power Measurement Modules
With the WAGO three-phase power measurement module in a DIN-rail-mount enclosure, WAGO offers the ideal solution – remotely from the control level – to measure currents and voltages in a three-phase supply network. Measured variables such as active/apparent/reactive power, energy consumption, power factor, phase angle and frequency can be accessed via Modbus® interface. Two integrated RJ-45 sockets streamline the interconnection of up to 32 devices.
Advantages:
- Measurement via current transformers or Rogowski coils › Flexible selection of upcoming measurement tasks
- Slot for microSD cards: Fast and secure mobile measurement, including recording
- Compact device in DIN-rail-mount enclosure: Saves space used for building technology
- Digital signal output as pulse output (pulses/KWh are configurable) › Permanent energy consumption monitoring
