ZigBee wall-mounted Energy Meter

The ZR-HMETER.W-M is a meter for electric energy and is part of the ZB-Connection range. It includes a 70 Amp power transformer to measure the real power up to 15 kW.

Moreover, it has a digital outout to pilot a high power external relay. Moreover is available stand-by killer and override button functions. You can set a power limit under which the device is meant to be in stand-by killer mode and so the external relay can be automatically turned off. With the override button the user can override the last command from the Gateway. Such tasks are carried out after simple Modbus commands sent to ZB-Connection network that transform them in wireless command.
The device is continuously supplied by a 230 Vca output, so it can also work as a repeater or a “father” device for battery supplied sensors.
