CE Marking

80kV, 320W X-Ray Source

Spellman’s XRB80PN320 Monoblock® X-Ray source is designed for OEM applications powering its internal X-Ray tube up to 80kV at 320W. Features like small package size and RS-232 digital interface simplify integrating this Monoblock® into your X-Ray system. Standard models are available with fan shaped beam geometry. Proprietary emission control circuitry provides excellent regulation of X-Ray tube current, along with outstanding stability performance.

Typical applications:

  • X-Ray Scanning: Food Inspection
  • Fill Level Confirmation
  • Security Applications
