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

Input Voltage:
20W:
24Vdc ±1V @ 2.5A
50W:
24Vdc ±1V @ 4A
X-Ray Tube Voltage:
Nominal X-Ray tube voltage is adjustable between 35kV to 80kV
X-Ray Tube Current:
20W:
0-250µA over specified tube voltage range
50W:
0-700µA over specified tube voltage range
X-Ray Tube Power:
20/50W, maximum continuous
Voltage Regulation:
Line:
±0.5% for a ±1V change of nominal input line voltage
Load:
±0.1% for a load change of 25µA to maximum rated current
Voltage Accuracy:
Voltage measured across the X-Ray tube is within ±1% of the programmed value
Voltage Risetime:
Ramp time shall be =250ms from 10% to 90% of maximum rated output voltage
Voltage Temperature Coefficient:
≤100ppm/°C
Over Temperature Fault:
Indicates that the internal oil temperature has exceeded 65° C. The high voltage output will be disabled. Toggling the X-Ray ON Command OFF and ON will reset the fault.
Over Voltage Fault:
An overvoltage (OV) fault is detected when the output voltage exceeds 82kV. The high voltage output will be disabled. Toggling the X-Ray ON Command OFF and ON will reset the fault.
Voltage Ripple:
1% peak to peak
Current Regulation:
Line:
±0.5% for a ±1V change of nominal input line voltage
Load:
±0.5% for a voltage change of 35kV to 80kV
Current Accuracy:
Current measured through the X-Ray tube is within ±2.5% of the programmed value
Over Current Fault:
An overcurrent (OC) fault is detected when the emission current exceeds 275µA (20W model) and 710µA (50W model). Toggling the X-Ray ON Command OFF and ON will reset the fault.
Arc Intervention:
One arc fault. The high voltage output will be disabled. Toggling the X-Ray ON command OFF and ON will reset the fault.
Filament Configuration:
Internal high frequency AC filament drive with closed loop filament emission control
