Product description
The PQRM5100 31 … Three phase multifunction Power Transmitter suitable for the measuring of 51 different parameters of the three phase power network:

• the TRMS values of phase voltages and phase currents
• active power, reactive power, apparent power and power factor per each phase
• +active energy, -active energy, inductive energy, capacitive energy per each phase and per 3 phase
• frequency, phase angle, line voltages, phase angles between phase voltages.

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 31… 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 31 … has two power supply versions 24 VDC ±10% (PQRM5100 31 …) or 230 V AC/DC ±10%
(PQRM5100 31 … PS).
