Modbus Three Phase Power Analyzer

General Description

The QE Power T is a Modbus Three Phase Power Analyzer that measures the following.

  • Voltage rms, Instantaneous Peak, Average and Max.
  • Current rms, Instantaneous Peak, Average and Max.
  • Power Active W, Reactive VAR, Apparent VA.
  • Frequency, Min and Max.
  • Power Factor total and per phase Inductive and Capacitive.
  • Energy kWh total and per phase.
  • Bidirectional Energy kWh positive and negative total and per phase.
  • Active and Reactive Energy kVARh Inductive and Capacitive total and per phase.
  • Crest Factor total and per phase.
Please see the register table for complete list of parameters measured with the Modbus Three Phase Power Analyzer. The Modbus Three Phase Power Analyzer can accept voltage up to 500V RMS and current transformers with an output of 1 or 5 AMPs. The QE Power T can also accept signals from Rodowski probes.
The unit is mounted on a DIN rail and is configurable with free software available from our website. Isolation is provided up to 4000 Volts between the measuring points and the Modbus output and 1500Volts between the Modbus output and the power supply.
