DKM-409 NETWORK
ANALYSER
WITH HARMONIC MEASUREMENT
AND SCOPEMETER
The DKM-409 is a precision instrument
designed for displaying various AC
parameters in 3-phase distribution panels.
Thanks to its isolated RS-485 Modbus RTU
communication port, the device is free from
ground potential difference issues and
measured parameters are safely transferred
to factory and building automation systems.
The power supply of the unit is isolated, thus
the same device can be used in both
230/400V and 120/208V systems.
The graphic screen allows display of
waveforms and harmonic analysis graphs.
Various display screens can be scrolled
automatically. The user configurable screen
where any measured parameter set can be
displayed, transforms the unit to a custom
designed measurement panel.
