Energy Metering

Milesight CT103-868M is an intelligent LoRaWAN® current transformer designed for wireless RMS current measurement up to 250 A in a single conductor. The split-core design enables installation without disconnecting the monitored circuit, while 3,3 kHz sampling makes it possible to capture dynamic load changes. Accuracy is ±1% for currents above 5 A and ±3% for values up to 5 A, with 1 mA resolution.

Variant CT103-868M operates in the LoRaWAN® EU868 band and supports OTAA/ABP Class A. The device can be powered by energy induced from the monitored conductor or by 5 V via USB-C, and the current version enables regular reporting with self-powering starting from 3 A at a 1-minute interval or 2,8 A at 10 minuteses. The transformer opening has a diameter of 16 mm, and the device supports alarms, optional cable temperature measurement and FUOTA updates.

Milesight CT105-868M is an intelligent LoRaWAN® current transformer designed for wireless RMS current measurement up to 500 A in a single conductor. The split-core design enables installation on an existing installation without disconnecting the conductor, while the 3,3 kHz sampling frequency allows rapid detection of load changes. Accuracy is ±1% for currents above 5 A and ±3% for values up to 5 A, with 1 mA resolution.

Variant CT105-868M operates in the LoRaWAN® EU868 band and supports OTAA/ABP Class A. The device can be powered by energy induced directly from the monitored conductor or by 5 V via USB-C. The current version reports data with self-powering from as low as 5 A at a 1-minute interval or 4,7 A at 10 minuteses, supports threshold and overrange alarms, an optional NTC temperature sensor and FUOTA updates.

Milesight CT303-868M is a smart three-channel LoRaWAN® current transformer designed for wireless RMS current measurement up to 300 A per measurement channel. The split-core design allows the transformers to be installed on existing conductors without disconnecting them, and one module can monitor up to three phases or independent circuits. The device offers ±1% accuracy, 1 mA resolution and sampling at up to 3,3 kHz.

Variant CT303-868M operates in the LoRaWAN® EU868 band and supports OTAA/ABP Class A. It can be powered by energy induced from the monitored conductor or by 5 V via USB-C, and the current version enables regular reporting from as low as 3 A at a 1-minute interval or 2,5 A at 10 minuteses. Threshold and overrange alarms, optional NTC cable temperature measurement and FUOTA updates are supported. The transformer opening has a diameter of Ø24,2 mm.

Milesight CT305-868M is a smart three-phase LoRaWAN® current transformer designed for wireless RMS current measurement up to 500 A per measurement channel. The split-core design enables installation on existing conductors without disconnecting them, and one module can simultaneously monitor up to three phases or independent circuits. The device offers ±1% accuracy, 1 mA resolution and sampling at up to 3,3 kHz.
