Compact, long rangesite configurable transducers

PT3 is a range of compact, configurable single-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.

Features

  • Best in class response time
  • Long range, site-configurable inputs and outputs
  • Load-independent accuracy on all outputs
  • Diagnostic LEDs
  • Compact footprint
