MINIVAC DESCRIPTION

The MiniVac controller is a quarter rack solid state
power supply with self protection features, which
generates high voltage using high frequency switching
technology.
The MiniVac ion pump controller is designed to operate
any type of ion pumps:
Triode and StarCell.
The MiniVac controller is a very compact and light unit
capable of powering any size of pump at different
operating pressure.
Small pumps (up to 8 l/s) can be operated at any
-3
pressure up to 1 x 10 mbar.
Medium pumps (20 l/s to 60 l/s) can be operated at any
pressure up to 1 x 10
operation).
Large pumps (120 l/s to 400 l/s) can be operated at any
pressure up to 2 x 10
operation).

MiniVac Controllers
Medium/larger ion pumps must first be started with an
appropriate control unit and pumped to a sufficiently
low pressure where the current demand is below 8 mA.
The MiniVac controller is designed to withstand
continuous operation at short circuit condition, without
any damage to the ion pump or to the controller itself.
The MiniVac controller is available in four versions,
which differ in the factory-set input voltage and in the
high voltage output connector type.
