1.1 Description of the
XRBHR/XRBD MONOBLOCK
Series
he XRBHR (high reliability) and XRBD Monoblock®
X-ray source are designed for OEM applications. The
XRBHR/XRBD Monoblock® series is equipped with
an internal Bipolar X-Ray tube designed for use at voltages
up to 80k, 100kVor 160kV at power levels up to 100W,
210W, 350W or 500W. It is a complete integrated system
consisting of a high voltage power supply (HVPS) with
proprietary control and protection circuitry as well as a
filament supply, X-ray tube and oil encapsulant in one
compact enclosure. Additional advantages are the
elimination of high voltage cables and low leakage X-ray
radiation.
A Power factor corrected input regulator is utilized to
improve overall reduction in harmonic emissions and EMI.
The output provides a reg390VDC to downstream
switching circuitry enabling optimal performance and
efficiency.
The
XRBHR/XRBD
MONOBLOCK
Series
incorporates remote programming, monitoring, and fault
indicators including interlock.
The X-ray source is a sealed unit containing the HVPS, X-
ray tube and insulating oil. The insulating oil provides
electrical insulation for the high voltage components and
the X-ray tube. The oil also functions as a coolant to carry
heat away from the tube. The cooling system requirements
are outlined in Chapter 3 and in the XRBHR data sheet
SHV#128132-001 or XRBD data sheet SHV#128146-001.
A bellows internal to the X-ray source compensates for the
expansion of the oil as the oil temperature varies thereby
eliminating the need for a bulky overflow tank.
The XRBHR/XRBD is available with either a fan or cone
shape beam geometry. Proprietary emission control
circuitry provides excellent regulation of X-ray tube
current, along with outstanding stability performance. The
XRBHR is designed for long field life and comes with a
three-year warranty for standard units.
