3.3. Operating principle
Area of application A PQRM5300 33 Ux Ix xx xx (PS) Three-phase Power
Meter measure the characteristic for three-phase network
system. The measured values are displayed on a graphic
display, and they are forward for processing units.
Programming and adjustment are performed via the front
panel membrane keypad.
The current inputs of the instrument are isolated from the
network with wideband current transformers. The voltage
inputs of the instrument are galvanic connection in the
network. The PQRM5300 33 Ux Ix xx xx (PS) Three-phase
Power Meter has many measurement configurations.
Options:
• Two (4-20 mA / 0-20 mA) or (0-5 mA / 1-5 mA) galvanic
isolated, configurable, scalable analog output.
• RS485 galvanic isolated communication output with
MODBUS RTU / ASCII slave protocol. 32 instruments can
be connected to the PLC or to the computer.
• ETHERNET galvanic isolated communication output with
MODBUS TCP protocol.
One options can be installed (dual analog output or
communication output) at the same time.
Operating principle
The signals of voltage divider output and of current-
transformer output through the signal conditioner and
protection circuits are led to the 16 bit A/D converter inputs.
The digitalized signals are processed by the instruments
microcontroller. The calculated energy values (+E, -E, +RE,
-RE) and the settings are stored an EEPROM for an
unlimited period of time. The switched-mode power supply
of the instrument produces two galvanic isolated output
voltages: one for the instrument circuitry and one for the
installed options.
Power supply The instrument has two power supply version:
