The XL series is based on the HW, and XF
series. It includes a 100W bipolar acceleration supply, and an isolated
filament supply whose power is controlled to stabilise the beam
current . It is intended to operate an X-ray tube in bipolar mode
which minimises the voltage potentials with respect to Ground. The
High Voltage section being mounted in the oil tank adjacent to the
X-ray tube, eliminates the need for high voltage connectors. Control
of the output voltage & current is by external 10 volt analogue
control voltages. All units are short circuit proof and use high
frequency pulse width modulated switching techniques, in conjunction
with a ferrite step-up transformer to control the output voltage.
We manufacture a large number of customized OEM versions of this
PSU, and would be pleased to discuss your application with you.
