The maximum-rated peak tube potential is 80 kVp and the maximum rated continuous tube cur-
rent is 1.2mA for the maximum-rated peak tube voltage.
The Radiation port contains filtration of 1.5mm aluminum. The measured half-value layer is
0.52mmAl at 80kVp. The measured value corresponds to aluminum equivalent of 2.5mmAl.
100, 117, 220-230, 240V~ ±10%. Line voltage regulation 10%.
Maximum 15 Amperes at 100 V~, 8A at 230 V~
80kV / 12mA
1.5kW, duty cycle approximately 1:10. The wait period is calculated using the following formula:
t = f(HS - HS ) - f(HS
w MAX 1
where HS = maximum tube anode heat storage capacity (28 kJ)
MAX
HS = current tube anode heat storage
0
HS = heat storage caused by next intended exposure (kV x mA x s)
1
f = tube anode cooling rate as a function of heat storage (given by tube manufacturer)
±2.5kV
±1mA

The beginning and end points of the exposure time are defined at 70% of the peak radiation
waveform measured with a calibrated x-ray monitor.
Is defined as the measured high voltage mean value measured with a calibrated non-invasive
kVp meter.
Is defined using the resistance and voltage over the feedback resistor measured with a calibrated
multimeter. The mA value is then the voltage divided by the resistance.
