300-1200W Industrial X-Ray Generators

Spellman’s new DXB Series of bipolar X-Ray generator modules are designed for OEM applications up to 140kV (±70kV) at 1200 watts. Its universal input, small package size and choice of three standard digital interfaces simpli­fies integrating the DXB into your X-Ray analysis system. DSP based emission control circuitry provides excellent regulation of emission current, along with outstanding stability performance.

Typical applications:

  • Plastics Sorting
  • Crystal Inspection
  • Plating Measurement
  • Thickness Gauging
  • Food Inspection
  • Mineral Analysis
  • X-Ray Fluorescence
  • X-Ray Diffraction
