PRO AT
NETWORK
ANALYSER
The DKM-409-Pro-At is a precision instrument
designed for displaying, logging and remote monitoring
various AC parameters in a 3-phase network.
The power supply of the unit is isolated. The standard
supply range is 100-265V-AC and 88-400V-DC
allowing universal use in AC and DC systems.
The unit has 3 x 4-20mA analog outputs. Any
measurement can be output as analog value.
The unit has 4 digital inputs and 2 relay outputs with
programmable functionality, selected from a list.
Thanks to its isolated RS-485 Modbus RTU comport,
the device is free from ground potential difference
issues and data are safely transferred to automation
and monitoring systems.
The device has 1MB internal memory for the record of
all electrical parameters with required frequency.
Records are read through Modbus.
The graphic screen allows display of waveforms and
harmonic analysis graphs.
The user configurable screen where any measured
parameter set can be displayed, transforms the unit to
a custom designed measurement panel.
