80-640W Industrial X-Ray Generators

Spellman’s XRF Series x-ray generator allow for a wide range of input voltages and supply either 80W, 320W or 640W of output power at up to 160kVdc. These lightweight rack-mountable X-ray generators house a miniaturized high voltage system in a solid encapsulated, oil-free design. The XRF Series x-ray generator is designed with a power factor corrected input circuit which reduces harmonic emissions and noise normally associated with other high frequency switching power supplies. The XRF Series x-ray generator incorporates an internal floating filament and a closed-loop emission control circuit for precise regulation of emission current. Remote monitoring and control of voltage, current and filament current is also provided.

Typical uses of the XRF x-ray generator are:

  • X-ray Inspection
  • Non-Destructive Testing
