DKM-405 NETWORK ANALYSER
WITH TOTAL HARMONIC DISTORTION DISPLAY
INTRODUCTION
The DKM-405 is a low cost precision
instrument designed to display various AC
parameters in a 3-phase distribution panel.
The standard unit is designed for 230/400V
network. A different version is available for
120/208V systems.
The harmonic analysis is available for up to
31 harmonics. THD values of both voltage
and current inputs are available.
The optional digital input accepts both AC
and DC signals and has programmable
functions.
The optional relay output is programmable.
Relay function is selected through a list.
The unit fits into a standard 92x92mm panel
opening.
