Industrial X-Ray Generators DXB Series 300-1200W

Spellman’s new DXB Series of bipolar X-Ray generator modules are designed for OEM applications up to 320kV (±160kV) 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
Cargo Screening
