The iWattMeter provides precise measurements of power consumption at an attractive price. It can be used in private homes and companies and ensures a relatively short payback period.
The iWattMeter is an intelligent electric power meter that records your current power consumption in kilowatt hours (kWh). Thus, you get your total power consumption in real time and to the second.
The iWattMeter is delivered including all necessary current transformers and connecting cables.
Here you can download the installation instructions and EU Declaration of conformity (CE Certificate).
Supports 50 Hz or 60 Hz networks with current measurement up to 100A and voltage measurement from 110V to 400V.
Supports standards EN 50470-1, EN 50470-3, IEC 62053-21, IEC 62053-22 and IEC 62053-23.
Compatible with 3-phase, 3 or 4-wire meters (Delta or Wye) and other 3-phase services.
Provides the total (fundamental and harmonic) active, reactive and apparent power as well as basic effective / reactive energy in each phase and in the whole system. Detects phase order.
Collects high-precision real-time properties with 1% error (typical) in active and reactive energy over a dynamic range of 3000 to 1 at TA = 25 °C.
Sends the measured characteristics at least 4 times per second using the MQTT protocol
Can be installed on the DIN rail.
