I've had a request for information about trigger voltage (and the possibility of using this flash on a digital camera). I don't have data, but I'll bet large that the trigger voltage of this unit exceeds 100v and may easily be as high as 200v. So, the answer is please do not hook this up to your digital camera. If you are buying this to use with such a camera, please consider using it with a peanut slave (or one of the safe flash connections that reduces trigger voltage to something like 5~10 volts). Flash units with trigger voltages this high were designed for use with real men's cameras. Not to say your digital camera isn't a real man's camera, but trigger voltage like this could make it look like a fly caught in a bug zapper.
