The ZR-HM3 is an electricity meter designed to measure the electrical consumption in civil, commercial and industrial applications. It can monitor voltage, current, power and energy from two three-phase lines or from six single-phase lines. Thanks to the external current transformer it can measure the phase true current up to 100A, the real time power up to 50 kW and has an energy counter. All the functions are activated by simple ModBus commands issued to the Gateway that transforms those commands in wireless commands. The device is continuously powered by 230 Vac; therefore it can also act as a repeater or a parent device for battery powered sensors.

Key features:

  • Real Time three phase Electricity Active Power or six single phase Electricity Active Power
