Description

The Milesight CT103 is an industrial-grade LoRaWAN Smart Current Transformer engineered for high-capacity 300A energy monitoring. Designed with a flexible, detachable split-core clamp, the CT103 enables safe and rapid installation on live industrial conductors without requiring facility de-energization. With a superior 3.3 kHz sampling frequency, it provides precise RMS current data and accumulated energy usage insights. Truly sustainable, the CT103 is self-powered by the magnetic field of the cable it monitors, eliminating the need for external power sources or battery maintenance in smart factories and large-scale commercial buildings.

Advanced Power Analytics

Energy Harvesting The device is fully autonomous, drawing its operational power directly from the electromagnetic field of the measured conductor.

Rapid Alarm Response Features a 1s sampling rate for threshold monitoring, triggering an immediate LoRaWAN alert if current levels deviate from safe parameters.

Professional Deployment Scenarios

• Industrial Motor Monitoring: Track the load and performance of large 300A industrial pumps and motors.

• Commercial Energy Auditing: Sub-meter main distribution lines in office complexes to identify energy waste.

• Machine Failure Prevention: Detect abnormal current draw in heavy machinery to schedule maintenance before downtime occurs.
