compact, long range site configurable transducers

DPT300 is a range of compact, configurable multiple measurand transducers designed to meet the demanding needs of supply utilities and industrial applications. It offers accurate true-RMS measurements for high efficiency and quick response time. It is equipped with up to four load-independent, galvanicallyisolated analogue outputs that can be configured for desired measurands, input range and different curves. DPT300 transducers comply with IEC 60688.

Features

  • Best in class response time
  • Long range, site-configurable inputs, outputs and measurands
  • Load-independent accuracy on all outputs
  • 4-in-1 programmable transducers
  • Diagnostic LEDs
  • Compact footprint
