A230 POWER MONITOR 

A230 Multifunctional Programmable Power Meter for 3-Phase Systems

The A 230 is designed for application in high, medium and low voltage systems. Any current and voltage transformers are taken into account in the calculation of the measured values.
The display instrument has dimensions 144 x 144 x 46 mm, and is suitable for mounting in a control panel. With 4-quadrant measurement, it is suitable for system and load analysis in single and multiphase AC systems.



Multifunction Programmable Panel Power Meter

  • Accurate measured values: U, I: 0.2%P, Q,
    S, PF, meter: 0.5% F: 0,02 Hz
  • 4-quadrant measurement of all values in AC systems
  • Clip-on extension module with average value and load profile recording, RS-232/485 interface, MODBUS, synchronizing input, switchover of
    high low tariffs
  • Safe 3-way galvanic isolation between all circuits
    2 outputs for pulse or limit values
  • 4 meters for active power: Incoming/outgoing with high/low tariff*
  • 4 meters for reactive power: Inductive/capacitive or incoming/outgoing with high/low tariff*
  • All counter values, recorded values, and settings
    are kept on a power supply failure
  • System/application: Single-phase 3L balanced/unbalanced (Aron, Full),
    4-L balanced/unbalanced (Open-Y, Full)

The instrument measures the currents I1, I2, I3 and the voltages U1, U2, U3, the frequency, and the phase angles between the individual currents and voltages. All the other measurements are calculated
from these. The measurements are made internally via integrated current transformers.
Therefore it is possible to make direct connections without an external transformer.
Each input is sampled 32 times per cycle.
This allows measurements to be made including up to the 15th harmonic.

Basic instrument
Instrument with active and reactive energy counters. Digital outputs configurable as impulse output counters and/or limit value indicators. Comprehensive average value and max./min. value functions.
Harmonic analysis and THD measurement. Determination of the neutral wire current, asymmetry factor and neutral point voltage shift.

Extension module EMMOD 201
Clip-on extension module with RS 485/Modbus-RTU and RS 232 (switchable). Average value and load profile recorder with time synchronization or external synchronization signal. Digital input for tariff
changeover for energy counters and impulse outputs, or a synchronizing signal.
