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: Diode, Differential Diode, 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 pressure up to
1 x 10
Medium pumps (20 l/s to 60 l/s) can be operated at any pressure up
to 1 x 10
Large pumps (120 l/s to 400 l/s) can be operated at any pressure up
to 2 x 10
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.
