600-1200W Industrial X-Ray Generators

Spellman’s XLF Series of X-Ray generators are well regu­lated high voltage power supplies with output voltages to 60kV and very low ripple achieved through the use of advanced resonant conversion techniques. Extremely stable voltage and emission current outputs result in significant performance improvements over previously available technology. The XLF Series provides power, control and support functions required for X-Ray applica­tions including a regulated ac filament supply referenced to the cathode. These units also incorporate local and remote programming, monitoring, safety interlock, short-circuit and overload protection.

Typical applications:

  • Plastics Sorting
  • Crystal Inspection
  • Diamond Inspection

Electronic Component (Power Source)

XLF series is intended for installation as a component of a system. It is designed to meet CE standards, with conditions of acceptance often being: customer provided enclosure mounting, EMC filtering, and appropriate protection, and isolation devices. The XLF series is not intended to be operated by end users as a stand-alone device. The XLF series power supply can only be fully assessed when installed within a system, and as a component part within that system.
