Overview
The Milesight CT103-US915 is a LoRaWAN smart current transformer designed for remote energy monitoring and consumption analysis. It supports a maximum current of 250A with an accuracy class of 1. The device operates on the US915 frequency band, utilizing long-range wireless communication to transmit data without requiring physical wiring modifications. It features a clamp-on design for non-intrusive installation on single live wires.
Feature Summary
- Non-intrusive clamp-on installation eliminates need for power cutting or rewiring
- LoRaWAN connectivity enables long-range wireless data transmission
- Self-powered operation removes dependency on external power sources
- High-accuracy current measurement for reliable energy consumption analysis
Applications
- Circuit monitoring for real-time current value collection
- Energy management systems for consumption analysis
- Smart building infrastructure for utility tracking
- Industrial equipment monitoring for load assessment
Procurement Notes
Verify that the specific model suffix matches the required regional frequency plan (US915) for your target deployment area. Confirm compatibility with existing LoRaWAN network servers and gateway configurations before ordering. Ensure the measured current range does not exceed the 250A rating of the CT103 variant. Check for any firmware updates required for initial integration with your energy management platform.
Selection Notes
Select this model when non-invasive installation is critical and the monitored circuit carries up to 250A. The US915 region support is mandatory for deployments in North America. Consider the CT10x series if broader current options are needed, but verify that the specific CT103 variant meets the exact accuracy and range requirements for the intended application scenario.
Part Context
The CT103 belongs to the Milesight CT10x series of LoRaWAN smart current transformers. This family includes variants like CT101 and CT105, offering different current ranges. The CT103 specifically targets higher current applications up to 250A while maintaining the same compact, clamp-on form factor and wireless communication standards as its siblings.
Replacement Considerations
Direct substitutes within the same product line include the CT101 or CT105, provided their current ratings align with the application needs. Cross-brand replacements require verification of LoRaWAN protocol compatibility and frequency band alignment. Ensure any alternative device supports the same installation method and data reporting intervals.
