Spellman’s DF/FF Series of X-ray Generators feature our new inverter design which incorporates IGBTs for power switching and provides new levels of reliability. In addi­tion, re-engineering of the DF/FF’s internal filament power supply eliminates audio noise at normal operating levels by operating at a higher frequency. The DF/FF’s utilize a sine wave current source, produced by phase shifting series resonant circuits at switching frequencies greater than 20kHz to generate high voltage dc. This technique eliminates undesirable electromagnetic radiation normally associated with switching and power control regulators. The high efficiency of these units allows for air cooling in a 5 1/4” (3U) high chassis.

Typical applications:
X-ray Diffraction (XRD)
X-ray Fluorescence (XRF)

Spellman’s XLF Series of X-Ray generators are well regu­lated high voltage power supplies with output voltages to 60kV and very low ripple achieved through the use of advanced resonant conversion techniques. Extremely stable voltage and emission current outputs result in significant performance improvements over previously available technology. The XLF Series provides power, control and support functions required for X-Ray applica­tions including a regulated ac filament supply referenced to the cathode. These units also incorporate local and remote programming, monitoring, safety interlock, short-circuit and overload protection.

Typical applications:
Plastics Sorting
Crystal Inspection
Diamond Inspection

  • 160kV Output Voltage
  • Rack-Mountable
  • Floating Filament
  • Internal Grid Power Supply (80W Model)
  • Power Factor Correction
  • Closed-loop Emission Control
  • OEM Customization Available

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
