High Voltage DC Input Signal Converter

Our range of AC Current and Voltage transmitters have been adapted for use as High Voltage DC Input Signal Converters.

A precision voltage divider forms the input stage for accurate and repeatable measurements. Galvanic isolation between input and output is provided after input conversion process.

Optional digital filtering can be used for the filtering of noisy signals. Options include signal inversion and a variety of output signal types.
