The DK-45 is a high-tech products providing control and protection of screw or piston type air compressors driven by electric motors. The unit incorporates all functions needed in a compressor control panel. Thus no additional modules are necessary resulting in lower panel cost.
The “early start” function analyzes the air consumption trend and runs the compressor so that the pressure never falls below the low limit.
The unit is directly supplied from the 230/400V utility network. It provides fail contact and sensor supplies internally, removing the need for a supply transformer in the panel. Utility mains voltages and frequency can be read on the unit. It offers low/high voltage and phase order protections.
The 2.9” wide, 128x64 pixels graphical screen displays values in bigger size and with graphic support.
Read More...The logic level Modbus RTU communication port of the unit allows computer connection providing monitoring and program parameter adjusting. Optically isolated digital inputs feature noise filtering allowing fault-free operation in electrically noisy environments.
The unit provides 5 relay outputs rated at 5 Amps. The unit configuration may be done through the front panel or using the free PC software.
The PC software is available for free download at manufacturer’s website. It is possible to monitor and record the unit using the free RAINBOW+ software.
