X-RAY POWER SUPPLY MODULE
HITEK POWER® XRG70
Exceptionally
small and
reliable
for high-
performance,
compact x-ray
applications
Specifically developed for high-performance, compact
x-ray applications,
the XRG70 series is exceptionally
small and reliable. It offers superior high voltage stability,
stress control, and packaging. This series includes a
variety of models from 25 to 90 kV, and is based on the
grounded filament series of products for grounded cathode
applications. The filament is automatically controlled by the
integral beam current loop-control, and the power stage
utilizes a current-fed resonant push-pull converter to provide
high efficiency while ensuring reliable operation.
Features
