PT3 is a range of compact, configurable multiple-input transducers designed to meet the demanding needs of supply utilities and industrial applications. It offers accurate true-RMS measurements and quick response time. It is equipped with up to four load-independent, galvanically-isolated analogue outputs that can be configured on site for different input parameters, input range and output curves.
