Home | Network Analysers | DKM-405 Network Analyser



The DKM-405 is a low cost precision instrument designed to display various AC parameters in a 3-phase distribution panel.

The unit features a 32-bir ARM based microprocessor. Thanks to its sampling rate of 4096s/s it reaches 0.5% precision range.

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.
