Product description

The PQRM5100 11 … Single-phase multifunction Power Transmitter suitable for the measuring of 12 different parameters of the singlephase power network:

  • The TRMS values of phase voltage and phase current
  • active power, reactive power, apparent power and power factor
  • + active energy, – active energy, inductive energy, – capacitive energy
  • frequency, phase angle.

The voltage inputs of the equipment are resistor networks (nonisolated) and the current inputs are isolated from the network with wideband current transformers. The current inputs 0-5 AAC or 0-1 AAC, and the voltage inputs 0-125 VAC / 0-250 VAC are in compliance with the requirements for measurement category CAT III.
The PQRM5100 11… is available with the following output options:

  • 2 × 0-20 mA / 4-20 mA galvanic isolated, scalable, active analog current outputs *
  • MODBUS RTU galvanic isolated communicatoin which makes possible the reading of all measurement values via the communication line, with a PLC or with a PC *.

(* only one option at the same time)

2 energy pulse outputs / limit outputs for limit-switching and for simple control tasks.
The measurement and output parameters are configurable from PC via USB port with the help of a user friendly configuration software. The configuration software is free of charge.
The PQRM5100 11 … has two power supply versions 24 VDC ±10% (PQRM5100 11 …) or 230 V AC/DC ±10%
(PQRM5100 11 … PS).
