A compact turbo controller with a large clear graphical display, an intuitive user interface and serial communications providing full remote control and data logging functions via a new Windows™ based PC program. The controller automatically recognizes and supports one 24 V turbomolecular pump from the nEXT range. Cooling and vent valve support is provided directly from the controller. Mains backing pumps (up to nXDS20i/RV12) may be controlled via an optional relay box. 2 different power variants are available, 100W or 200W which determines the ramp speed of the turbo pump. In addition 200W models have the ability to power a 24Vdc backing pump such as our XDD1 or nXDS through a 15-way D. Turbo and instrument models add the ability to control up to 3 of our range of Active gauges (excluding IGC & Barocels).
