DK-40 COMPRESSOR CONTROLLER
INTRODUCTION
DK-40 is a state of the art unit for the control
of both screw and piston type compressors.
The unit integrates all functions needed in a
compressor system. Thus no extra units are
required in a compressor panel providing
cost reduction and simplicity.
The unit is directly powered from 230/400 volt
mains. It provides power supply for fault
switches and sensors. Thus external
transformer is not required in the panel.
The unit monitors mains phase voltages and
frequency. It features high/low voltage and
phase order protections.
The standard logic level serial port features
MODBUS communication. The unit allows
monitoring and programming through
computer.
