    Hi
    I need some advice finding a solution to my problem:
    I have a slave clock (mechanical) which requires a 48V input, with alternating current every 60s.

    I've bought an impulse driver which only outputs 24V, which is not enough to make it run. The clock works because I have tested it manually (switching the plug pins by hand with 48V input).

    What I need is something like a universal impulse driver, something like this I am guessing:
    http://www.allspectrum.com/store/universal-impulse-driver-c-101.
    But they don't make them anymore..

    Does anyone know where I can get this? Or else I will have to make something to fit my needs. I am new to circuitry and it would be great to have your advice on where to start - are there kits for this type of thing?

    Does it need 48v dc or ac, you can use the mains frequency as the timebase, with a 48v transformer and a counter divider to give a pulse every 60seconds. Or use a xtal clock with a cd4040, cd4060 chip.

    What is the required duration of each AC pulse?

    The Simplex ones I used to work on required a 1 second pulse every 59 seconds. It was 24 vdc. don't remember the model no.

    Thanks for all your feedback. To be more specific:
    I need an off-the-shelf product which gives a 48V alternating pulse ( + and -) every minute (less than 1s, not sure exactly how long).
