Project Description

Energy Meter 1~ ZigBee Modbus Print datasheet

ZigBee bidirectional wireless power meters with current transformer for single phase lines up to 15 kW
Main technical specifications
  • ZigBee bidirectional wireless power and energy meter
  • Max power measurement: 15 kW single phase
  • Split core current transformer included
  • Digital output for controlling an external relay
  • Router function within the ZigBee wireless network
  • Building automation and industrial control systems
  • Energy monitoring and management

Wireless energy meter for measuring the power of a load / single phase line up to 15 kW using a split core current transformer (TA)

In industrial applications, the device can be used to monitor a production line or a lighting line inside or outside a section.

The device is fitted with a digital output for controlling an external, high power relay.

Thanks to continuous power, the device can also function as a ZigBee signal repeater and as a parent device for battery powered sensors.
