100 V - 240 V~ ±10%
Maximum 15 Amperes at 100 V~, 8 A at 230 V~
96 kV / 12 mA
1.5 kW, 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)

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 maximum voltage difference over the X-ray tube. It is
measured with a calibrated non-invasive kVp meter.
Tube current is defined by measuring the voltage difference over mA
feedback resistors. The values of mA feedback resistors are known, so the
mA value can be calculated from the feedback voltage.
