Steve,
I had a look at the Aeroflash web site where it says that the power
supplies provide 450 volts dc to a capacitor which is parallel to and
discharged through the xenon flash tube when it is triggered. This
raises a few issues:-
- you could end up with both tubes in parallel with the one capacitor
leading to odd timing or even neither of the tubes working.
- the power supply will probably be some sort of inverter circuit
which will only draw a small residual current once the capacitor is
charged up, so the current saving will be limited.
- there is a definite time lag between the xenon tube flashing and
the capacitor re-charging for the next flash. There may not be enough
time to get to 450 v before the other tube is triggered.
- you will end up with long cable runs with 450 volts on them (even
when everything is switched off) - cannot be too safe!
- with removable wings, these long cables need to have some plugs and
sockets involved. Again with 450 volts on them, assembly/disassembly
could be hazardous.
All in all, I would suggest that you do not pursue this idea.
Regards,
Peter Barwick
