Single Phase Energy Meter Wall Mounted


The ZR-HM.W-M electricity meter includes an external 70Amp current transformer to measure real time active power up to 15 kW and has an energy counter.


Moreover it has a digital output to drive high power relay. Functions as stand-by killer and override push button are also available. It is possible to set a power limit below of which the load is considered in stand-by mode and therefore the external relay is switched off. With the override push-button the user can override the last relay order issues by the Gateway. All the function 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.
