OWER SUPPLY
The CP200 generator can be powered through the PowerBox from either the main grid, from a power
generator set or even from a car or truck battery with a DC to AC power inverter. Its electronic power circuits
enable it to adapt, without danger, to most fluctuations and sudden variations that may occur on some
networks.
Thanks to the very good power factor, the input current is limited to 6A @230VAC or 12A @115VAC. This
makes it possible to use the PowerBox with long power extension cables or small size power generators.
The PowerBox is equipped with a very accurate measurement of the power supply's voltage and frequency.
It constantly monitors and analyzes the input power's square root voltage, peak voltage and frequency. If
the input power goes out of the specified operating range, the PowerBox will automatically stop any ongoing
exposure to prevent damage to the equipment due to out of bounds input power.
4.1.2 P G
OWER
The PowerBox can be powered from electric power generator sets of nominal power equal to or greater
than 2 kVA to offer the full performances of the tube head.
The excellent power factor (voltage and current are in phase) guarantees smooth operation, without any
particular problems, with most existing models. The electrical power sets can be of "petrol" type with
electronic regulation or "diesel" with flywheel.
Voltage and frequency fluctuations should be less than 5%.
4.1.3 P
ROTECTIVE EARTH CONNECTION
The CP SERIES X-ray generator produces ultra-high voltage internally. For the electrical safety shut-off
devices to operate optimally in the event of failure or an accident, it is essential that the CP SERIES
generator or PowerBox are effectively connected to an earth of low impedance (< 10 Ohm).
This protective earth connection can be provided by the network (single-phase + earth) via the power supply
cable which comes with the equipment. You must however always check that the earth is connected to
ground in the supply circuit and that it does not exceed 10 Ohm.
If there is any doubt or in the case a generator set is used, it is strongly recommended that the visible earth
terminal of the PowerBox or CP SERIES generator, provided for this purpose, is connected locally to earth
(for example by using an earth rod), the value of which you should carefully check before use.
This is both for the safety of the equipment as well as for the safety of the operator!
