The GST-07L-B is a sputter ion pump controller which features sophisticated functions and high-grade reliability. It is the product of ULVAC’ s extensive technological reserves and long track record of proven performance in the ultra-high vacuum field.


  • Compact size and light weightMulti-function performance enabled by CPUControl of all sputter ion pumps (PST series) possible using one controller
  • Communication functions provided as standard featuresRemote control and automated operations are made possible by the external communication control functions which have been provided as standard features.
  • XHV supported Pump cell contamination can be reduced to the absolute minimum by the automatic start circuit and soft start functions. (-Patent No. 1340297, etc. pending)
  • Improved safety functionsThe controller comes with a function which prevents the erroneous operation of its function switches and with interlock functions for protection.Fluorocarbon resin high-voltage cables with excellent resistance to the heat and cold and superb electrical characteristics are used.Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS directive)-supportedCE marking-supported
