Single Phase Energy Meter


The ZR-HMD-M Energy Meter includes an external 70Amp current transformer to measure real time power up to 15kW 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 ZB-Connection 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.
