DKM-430
MULTIPLE NETWORK
ANALYSER
DATAKOM DKM-430 is a precision instrument
allowing the measurement, recording and remote
monitoring of 10 3-phased or 30 single-phased feeders
(or any combination of these two). The number and
flexibility of current inputs allow the unit to be used in a
variety of applications like power distribution network
monitoring, ISO50001 energy efficiency or home and
factory automation.
The unit can be mounted on a DIN rail or backplane. It
can be easily adapted to existing panels.
Current inputs of the unit are designed for 0.1A output
current transformers (CTs). Different 0.1A rated CTs
are available at Datakom for sales.
Each CT can be assigned to any phase voltage and
any virtual analyzer. Inputs can be moved between
analyzers without modifying connections.
Independently adjustable current limits for each phase
provide pre-alarms and help to reduce energy failures.
All measurement values and program parameters may
be displayed on the graphic LCD screen.
The unit logs all fault conditions together with date and
time information. The internal real time clock is capable
of running 10 years without energy.
The astronomical relay function calculates sunrise and
sunset times precisely for daylight based applications.
Any fault or warning signal can be connected to digital
inputs of the unit. Input functions are selected from list.
Any function can be assigned to relay outputs of the
unit. Relays may be remotely operated through the
central monitoring program.
The isolated RS-485 MODBUS RTU data port is
unaffected by ground potential differences and allows
safe transmission of information to monitoring and
automation systems.
The optional internal GPRS modem allows remote
monitoring and control of the distribution panel without
the use of any additional module.
Parameter setting of the unit is made either manually or
through the USB port using the free PC program.
The unit records electrical parameters in its 1MB
internal memory with programmed period. Records are
read through Modbus.
Equivalent to 10 3-phase analyzers

CONNECTING CTs:
Be sure of connecting each CT to the related phase input with the correct polarity. Mixing CTs between
phases will cause faulty power and pf readings.
Many combinations of incorrect CTs connections are possible, so check both order of CTs and their polarity.
Reactive power measurement is affected by incorrect CTs connection in similar way as active power
measurement.

The unit features waveform display together with a precision harmonic analyzer for both voltages and
currents. Both phase to neutral and phase to phase voltages are available for analysis, thus 36 channels in
total are possible.
Available channels are:
Main busbar volts: V1, V2, V3, U12, U23, U31
Currents: I1, I2, I3,….,I29,I30
Scopemeter Display
The waveform display memory is of 100 samples length and 13 bit resolution, with a sampling rate of 2048
s/s. Thus one cycle of a a 50Hz signal is represented with 41 points. The vertical scale is automatically
adjusted in order to avoid clipping of the signal.
The waveform is displayed on the device screen, and with more resolution on PC screen through the
RainbowPlus program.
The display memory is also available in the Modbus register area for third party applications. For more
details please check chapter “MODBUS Communications”.
The waveform display is updated twice a second. All channels may be scrolled using buttons.
