Product Description
Technical Details
The Milesight CT103-868M is an intelligent LoRaWAN® current transformer that enables real-time and accurate current measurement for smart buildings, electrical panels, and industrial energy systems. With a sampling frequency of 3.3 kHz, ±1% accuracy (above 5A), and a resolution of 1 mA, it ensures precise RMS current monitoring.
Its non-invasive clamp design makes it easy to install without disconnecting power, significantly reducing downtime and installation costs. The CT103 supports induced current power supply or USB-C power and integrates an NTC temperature sensor to monitor cable temperature, ensuring operational safety.
The device supports LoRaWAN® Class A connectivity and includes intelligent features like threshold alarms, overrange detection, and FUOTA (Firmware Update Over-The-Air). Configuration can be done via USB-C or downlink, and the device seamlessly integrates with Milesight gateways and cloud platforms for remote visualization and control.
Ideal for applications like:
-
Industrial energy monitoring
-
Machine health diagnostics
-
Smart building infrastructure
-
Power load detection
-
Cable overheating alerts
