Description

Overview

The Fronius Smart Meter CT 100A / 333mV is a current transformer accessory designed to extend the measurement capability of Fronius Smart Meters in larger photovoltaic systems. It enables accurate current measurement on higher-current circuits without the need to disconnect the power supply.

Using split-core technology, the transformer is simply installed around the existing cable, making it ideal for both new installations and retrofits. The measured current is converted into a 333 mV signal, which the Fronius Smart Meter then translates back into the original primary current using the defined conversion ratio.
