MultiTech CT300: Wireless LoRaWAN Current Monitoring Device

About the MultiTech CT300

The MultiTech CT300 (MTCT300) is a wireless and self-powered electrical current monitoring device. It is capable of reporting average, peak, and minimum RMS Amperes and tracking accumulated Amp-Hours. The device parasitically harvests energy from the monitored conductor, negating the need for routine maintenance to replace or charge batteries.

MTCT300 uses sub-gigahertz LoRaWAN for long-range wireless communications. This IoT interface can be deployed as a private network, or used with an available public one. The use of short data messages increases reliability of transmission in suboptimal environments such as metal electrical panels.

Device Overview

The CT300 unit features a communication module, antenna, USB power port, and a diagnostic LED. It connects to a split-core current transformer, which is designed to clamp around existing wiring for easy installation. The transformer has a latch mechanism for secure closure.
