Single Phase Modbus Harmonic Analyzer

Single phase modbus harmonic analyzer infographics.

The QE Current 485 H from Qeed has all the features of the QE Current 485 and also measures the Harmonic analysis up to the 63rd, the Total Harmonic Distortion, and the Current peak. The QE Current 485 H also measures the internal temperature of the unit. The QE Current 485 H provides registers for the Total Harmonic Distortion and a separate Register for each of the Harmonics as a float, the current peak and the internal temperature.
It can obtain the information from AC/DC current and voltage transformers, Rogowski Probes, and Hall Effect Sensors.
The free software is used to set up the QE Current 485 H on the Modbus protocol.
The Single Phase Modbus harmonic analyzer can be mounted on a DIN rail, and power and Modbus network can be connected to via an optional T-BUS connector.
