Radiation leakage technique factors
The maximum-rated peak tube potential is 80 kVp and the maximum rated continuous tube
current is 12mA for the maximum-rated peak tube voltage.
Minimum filtration
The Radiation port contains additional filtration of at least 1.5 mm aluminium.
Total filtration min. 2.5 mmAl.
When the X-ray beam is attenuated with the 3 mmAl the dose is reduced by factor 0.50-0.56
Maximum attenuation equivalent of the front panel of the
panoramic cassette holder
0.5 mmAl
Rated line voltage
100-132 V~, 180 - 240 V~. Line voltage regulation 10%.
Maximum line current
Maximum 15 Amperes at 100 V~, 8A at 230 V~
Technique factors that constitute the maximum line current
condition
80kV / 12mA
Generator rating and duty cycle
1.5kW, duty cycle approximately 1:10. The wait period is calculated using the following for-
mula:

where HS
MAX
= maximum tube anode heat storage capacity (28 kJ)
HS

= current tube anode heat storage
HS
1
= heat storage caused by next intended exposure (kV x mA x s)
f = tube anode cooling rate as a function of heat storage (given by tube manufac-
turer)
Maximum deviation of peak tube potential from indicated value
±5%
Maximum deviation of tube current from indicated value
±(5% + 0.5mA)
Maximum deviation of exposure time from indicated value
±8%
