Description

The Milesight CT105 is a professional-grade LoRaWAN Smart Current Transformer engineered for high-power industrial environments. Designed to handle loads up to 500A, the CT105 features a specialized large-diameter clamp with a 36.5mm aperture, allowing it to fit easily around heavy-duty main feeders and large industrial conductors. By utilizing 3.3 kHz high-frequency sampling, it delivers precision RMS and accumulated current data for granular energy analytics. With its non-invasive clamp design and energy-harvesting power system, the CT105 offers a maintenance-free, safe installation path for monitoring primary power distribution without site downtime.

Heavy-Duty Power Analytics

Self-Powered Operation The CT105 harvests its own operational energy from the magnetic field of the monitored line, eliminating the need for external power or battery changes.
Critical Threshold Alerts Equipped with high-speed 1s threshold sampling to trigger immediate LoRaWAN uplinks if current levels exceed industrial safety parameters.

Industrial Monitoring Scenarios

• Main Distribution Monitoring: Track the total load of primary electrical panels in factories and large commercial complexes.
• Heavy Machinery Analytics: Monitor 500A-rated industrial equipment, chillers, and compressors for efficiency and failure prevention.
• Predictive Maintenance: Identify subtle changes in high-current draw to schedule maintenance before critical system failures occur.
