Description
Description
The Milesight CT305 is a professional LoRaWAN® Smart Current Transformer designed for the intensive energy demands of heavy industry and large-scale commercial facilities. Engineered for a 500A rated primary current, the CT305 utilizes induced current power technology to harvest energy directly from the testing conductor, eliminating the need for batteries or external power wiring. Its non-invasive split-core design facilitates rapid, safe installation without interrupting operations, providing a scalable path to high-fidelity energy analytics.
Core Capabilities
Energy Management Use Cases
Technical Integration
The CT305 is fully compliant with LoRaWAN® Class A and supports global frequency bands. It features Over-the-Air Firmware Updates (FUOTA) and is equipped with a status/alarm LED for field diagnostics. When harvesting power from Phase A, the unit requires a minimum reporting current (30A at 1min intervals or 19A at 10min intervals). For lower current measurement or initial configuration, the device can be powered via its USB Type-C port. For professional system architecture support, contact the ShopIoT engineering team.
