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.

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.
