Product description

The PQRM5300 33 … 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 operating parameters of the device can be configured via the front panel push buttons via the graphical display menu system (current transformer, voltage converters, limit values, limit mode, output configuration, power limitation, etc.)
The PQRM5300 33 … has two power supply versions 24 VDC ±10% (PQRM5300 33 …) or 230 V AC/DC ±10% (PQRM5300 33 … PS).
