Eeeeek!!! Braun F910 Pro unit...

[J A Mortram]

Thanks for all the great replies : )

I'll bring it over to you soon Don... I just know I'll blow the house up if I even plug it in... me and electric things get on about as well as... well, water and electricity ; )

For sure, it's a cool looking beastie - hope we can get it to function in some fashion... : D

Thanks for the info folks - 275 Volts !

Safest bet with old units is to use a slave to trigger them with. All manual exposure though, to prevent the pre flash firing them.
Foxy did a thread on his experiences with a slave. I will do a search and link it.

Don, when I do use them and thats not often I use them with a slave trigger and they work well as secondary flash.

I posted this pic in a thread ages ago but cannot find it to post a link to the thread.

This should answer why old cameras could handle such high trigger voltages.
Note the scale of the copper contacts used on old cameras that handled the flash triggering current.

Before anyone asks, no, I am not going to open the D2X up to take a pic of its insides.

Same applied to the old 60 series Metz I use to have, and the even older 400 series Metz stuff with dryfits not much smaller than car batteries! lol
If I didn't get the fitting fully home on the hotshoe it would spark up blue on my old Contax RTS!

Yes, said before well worthwhile using as a slave via light or radio trigger.....otherwise keep it strictly for the older film cameras

Jim,

I have had a quick look since your dad left, and one of the boxes is a transformer. Tomorrow I will rig up a lead and see if it still works. If so you could be cooking with gas for a mains powerd 2 flash head set up.

Hey mate : )

AHHHHHHHhhhh!!! So THATS what that was!!!!!... I really hope to make it over next time Don so we's can have a good chat!!!

Hi Jim,

Time to get your head in gear for a bit studio flash.

Both units are now working from the mains power supply.
Its going to take some time to reform the capacitors before we can have some idea of the power output, but things are looking good, and I have stars before my eyes at the moment from the trial flashes.

Instruction manual is a bit lacking on info so I will need time to properly work them out. One unit is the master and the other a slave.

Jim,

Lights flashing before my eyes so enough for today. Two of these firing in the confines of my workshop for flash meter tests, its no wonder.

Update : Both units working off mains power.
One unit has controllable output through the remote sensor, eight stop range and that has been confirmed with a flashmeter. The slave is a full power all the time job with no facility to reduce power other than the diffuser panel which cuts one stop of light.

The battery is dead and there is a question mark over its charger . The dryfit battery is a Sonnenschein A200 8v 3.8Ah. No idea where a replacement of similar size and spec can be had nowadays. I have not tried cobbling a standard Nicad cells job as with a trigger voltage of 27.8volts it is not useable directly connected to a modern camera anyway. Power output is currently the same as a Metz 45, so one of those ( CL3 or CL4 0 with a suitable SCA unit to control the trigger voltage is a more compact powerful hammer head to attatch to a camera.

The Braun units will do a pretty good job in a controlled studio type environment though, so maybe tomorrow dependant on whats happening, I may well knock up a brolly holder to give them a proper go. I could do with taking some pics now they are cleaned up to post here anyway as these are probably fairly rare beasts.

AWESOME NEWS!!! How cool is that DON!!!???... you're a bloody genius mate!... can't wait to pop over and gleen some info... I'm planning, on maybe, time permitting, knocking a little studio up at home... I'll discuss the 'type' of image i'm after with you when I see you... then I will just leave the flash set for that shot etc... eeeeee! can't wait to see your results : D

Cheers mate and see you soon : )
