OQ Series Open Stack


OQ open stack series models consist of a rack style driver chassis, a high voltage stack assembly, and a remote control unit. The driver chassis is provided in a cabinet which is 10.86” H X 19.75” W X 25.06” D. The remote control unit is 5.218” H X 19.00” W X 6.625” D.

The OQ open stack family are sophisticated 8 kW power supplies with extremely low ripple and noise. They are air insulated fast response units with tight regulation

The OQ Series are fully compliant with the following European Directives:

  • EN61010/ IEC61010, Safety
  • EN61000-6-4, Conducted and Radiated Emissions
