80kV, 20-50W X-Ray Source
Spellman’s XRB011 Series of Monoblock® X-Ray sources are designed for OEM applications powering its internal X-Ray tube up to 80kV at 20W and 80kV at 50W. Features like 24Vdc input voltage, small package size, standard analog interface and RS-232/Ethernet digital interface simplify integrating the XRB011 into your X-Ray system. Proprietary emission control circuitry provides excellent regulation of X-Ray tube current, along with outstanding stability and performance.
Typical applications:
- Medical X-Ray: Fluoroscopy and Radiography for Extremities, Specimen Radiography.
- Pulsed Fluoroscopy (contact Spellman sales)
- Industrial X-Ray: Component inspection and Non-Destructive Testing
