1200W Industrial X-Ray Generators

Spellman’s new DXM100 X-Ray generator module is designed for OEM applications up to 100kV at 1200 watts. Its universal input, small package size and choice of three standard digital interfaces simplifies integrating the DXM100 into your X-Ray analysis system. DSP based emission control circuitry provides excellent regulation of emission current, along with outstanding stability.

Typical applications:

  • NDT Analysis
  • Plating Measurement
  • Mineral Analysis
  • Crystal Inspection
  • Diamond Inspection
  • Food/Product Inspection

12mA maximum

Output Power:

1200 Watts maximum

Output Voltage Regulation:

≤ 0.01% of rated output voltage over specified input voltage range

≤ 0.01% of rated output voltage for a full load change

Emission Current Regulation:

≤ 0.01% of rated output current over specified input voltage range

≤ 0.01% of rated output current for a change from 30% to 100% of rated output voltage

Filament is disabled when kV is <30% of full scale output 


≤ 1%rms at >20 kHz, 0.1%rms below 20 kHz


≤ 25ppm/hr after a 2 hour warm up

Temperature Coefficient:

≤ 50ppm per degree C


Temperature Range:

Operating: 0°C to 40°C

Storage: -40°C to 85°C


20% to 85% RH, non-condensing.

Filament Configuration:

Closed loop emission control regulates filament setting 
to provide desired X-Ray tube emission current.

Output: 5.0 amps at a compliance of 10.0 volts, maximum. The filament loop is disabled when the kV output is less than 30% of full scale output to protect the X-Ray tube. Other filament levels available on special order. 

Control Interface:

Local Interface:

Potentiometers are provided to adjust filament limit and preheat levels

Remote Interface:

USB, Ethernet and RS-232 are standard. All digital monitors have an accuracy specification of 2%

Control Software:

A Windows graphical user interface example is provided. Built-in diagnostics can be performed over Ethernet via a Java applet and any standard web browser

High Voltage Enable:

A hardware based, dry contact closure will enable the power supply into the high voltage on mode

Monitor Signals:

Voltage and current monitor signals are scaled 0-10Vdc equals 0-100% of full scale, accuracy is 1%

Over Power Fault:

 The maximum power the unit can supply can be programmed (0-1200 watts) via the digital interface, this setting will be stored in memory. An over power fault will occur if the output power is ≥ 105% of the set point value. When an over power fault occurs the high voltage output will be disabled and the Over Power Fault indictor will be activated on the GUI/Applet. Additionally both the UV and OV fault LED’s on the DXM100 will be illuminated.
