DATAKOM DKM-407 Electric network analyzer, DIN Rail, THD, RS-485, 1-input, 1-output

The DKM-407 is a DIN rail mounted precision and low cost unit allowing measurement and remote monitoring of AC parameters in a distribution panel.
Main applications are remote monitoring and energy management.
The unit is supplied between L1 and Neutral terminals. Thanks to the supply range of 85-305V, it is not affected by voltage fluctuations and is capable of operating in any network.
The unit features an 32-bit ARM core microcontroller. With a sampling rate of 4096s/s it reaches 0.5% measurement precision.
The unit provides harmonic analysis of all voltage and current channels, up to the 31th component.
The unit provides 1 programmable digital input and 1 programmable relay output. Input/output functions are selected from a list.
The isolated RS-485 MODBUS RTU data port is not affected by ground potential differences and allows safe transfer of data to monitoring and management systems.
Program parameters may be uploaded from a PC. The parameter setup and multiple-unit monitoring programs are free of charge and may be downloaded from the manufacturer’s website.
