Overview

The SynapSense® Three-Phase Wireless Current Sensor provides True RMS AC Current without

requiring service interruption. The SynapSense Constellation Node calculates the average current over a

five-minute collection interval and wirelessly reports this data to the host server via the SynapSense

Wireless Sensor Network (WSN). The use of non-intrusive Split Core Current Transducers (CTs) enables

sensors to be installed without having to disable the equipment being monitored.

SynapSense offers a wide range of CTs available from 100 to 4000amps in a wide range of sizes. The kit

includes three Split Core CTs, a Constellation Node, cable assemblies, and a 100 to 240VAC power

adapter for powering the CTs and node.
