Product Overview
The LEM TT 100-SD is a split-core AC current transformer designed for the electronic measurement of AC waveform currents. It provides galvanic isolation between the primary power circuit and the secondary measurement circuit. Key features include a 16 mm sensing aperture for non-contact measurement, a 1-meter cable output, and an isolated plastic case recognized according to UL 94-V0. This transducer offers high accuracy, low phase shift, and robust isolation, making it a cost-effective and easy-to-install solution for applications such as power meters, energy sub-meters, power quality monitoring, condition monitoring of motor loads, and distributed measurement systems within the Energy and Automation domain.
