Portaflash by Jessops

Hi everyone,
This question probably only applies to those folks, like me live in Great Britain. Does anyone know what the Trigger Voltage is for their equipment. As I'm a little concerned with some of the possible side effects this could have on the cameras internal workings.


Many Thanks

David

That can be an important thing for concern.

Why not simply measure the trigger voltage? That way, you don't have to depend on specifications that might or might not apply to your flash.

(1) Get a DC voltmeter. Set it for a scale of 250 volts or so.
(2) Turn on the flash unit.
(3) Find the place where it attaches to the camera, and this is likely to be a cable connector.
(4) Place the meter across the two pins of the connector.
(5) If you don't get much of a reading, then reduce the scale to 25 volts or so. Try it again.

Typically, the big Canon flashes are about 5 volts, which is safe. Lots of the old Vivitar flashes are 170 volts or so, and that is not safe for a Canon digital.

Thank you for your recent e-mail.

The trigger voltage for the 336vm head is 9 volts.

If you need any further information then please e-mail me.

Uhhh, check that.

The Canon digital camera spec is only 5-6 volts.

What are you going to get?
