Description

The CT103 from Milesight is a wireless LoRaWAN energy meter, equipped with a current clamp, to monitor energy consumption in for example residential as well as commercial applications.

The energy meter uses a current clamp, which makes it possible to easily measure without modifications to existing wiring.

The energy meter powers itself by means of a supercapacitor, so no batteries are needed.

The CT103 has a maximum measuring range of 300A and takes a measurement every second. Because the sensor has a sample time of 1 second, it is possible to determine energy consumption.

Configuration of the meter is possible via a LoRa downlink or by means of USB-C and the ToolBox app. This way you can set threshold values and alerts.

By default the energy meter is supplied with a bend antenna and 2 year warranty.
