Model XR150

X-RAY POWER SUPPLY

FEATURES
150W high voltage output
17W floating filament
Exceptionally compact size
Remote operation
Marked for EU LV Directive 2006/95/EC
EU RoHS Compliant to 2002/95/EC
High accuracy and stability

DESCRIPTION
The Series XR150 has been specifically developed for high performance
X-ray applications; the combination of surface mount, superior high
voltage stress control and packaging techniques ensures a compact
but highly reliable product. The Series XR150 is designed for use in
inspection and analytical X-ray systems with floating filament tubes.
The filament is automatically controlled by the integral beam loopcontrol and the power stage utilises a current fed resonant push-pull
converter to give high efficiency whilst ensuring reliable operation.
The Series XR150 is available with either an analogue or RS232
control interface. If the version you require is not on this datasheet
then please enquire as we produce many custom versions for specific
requirements.
