Electric Compressor Controller / DK-70 MK2































           DK-70 is a next generation compressor controller providing control of screw or piston type air compressors driven by electric motors.
           The same controller provides the combination of wide communication capabilities together with a reliable and
           low-cost design.


           The unit incorporates all functions needed in a compressor control panel; thus, it eliminates the need for additional modules,
           resulting in lower panel cost.

           The early start function analyzes the air consumption trend and runs the compressor before the pressure falls below the low limit.
           Using the Weekly Schedule Exerciser and Pressure Calendar functions, the compressor can be scheduled to work on given hours and
           days of the week with given set pressure values.

           The unit is directly supplied from the 400/230V utility network. It provides fail contact and sensor supplies internally, removing the
           need for a supply transformer in the panel.
           The unit complies and mostly exceeds world’s tightest safety, vibration and environmental standards for the industrial category.
           Software features are complete with easy firmware upgrade process through USB port. The Windows based PC software allows
           monitoring and programming through USB, RS-485, Ethernet and GPRS. The Rainbow Scada web monitoring service allows
           monitoring and control of an unlimited number of gensets through any web browser.
