DXM Series 300-1200W Industrial High Voltage X-Ray Generators

Spellman’s new DXM Series of X-Ray generator modules are designed for OEM applications up to 75kV at 1200 watts. Its universal input, small package size and choice of three standard digital interfaces simplifies integrating the DXM into your X-Ray analysis system. Models are available to operate either floating filament (negative HV polarity) or ground referenced filament (positive HV polarity), X-Ray tube designs. DSP based emission control circuitry provides excellent regulation of emission current, along with outstanding stability performance.

Typical applications:

Plastics Sorting
Crystal Inspection
Plating Measurement
Diamond Inspection
Mineral Analysis
X-Ray Fluorescence
X-Ray Diffraction
