    Hi,

    know a lil about electronics and electrical just want to make sure i'm not being a dummy or if there are any other better alternatives.

    Problem:
    A timed output circuit has gone bang on an piece of work equipment, wont go into detail as it may confuse the situation but it all works apart form the timed lamp button, I can see components on the lamp circuit disintegrated etc...

    So I wish to make the lamp part sort of stand alone.
    plan is to convert a 230v suply down to 12v 5a as the lamp it needs to power is 50w.

    Resolution:
    I was going to get this
    https://www.amazon.co.uk/200-250V-Halogen-Light-Electronic-Transformer/dp/B00CXK30UW
    and
    http://www.ebay.co.uk/itm/DC-5V-12V...-Time-Delay-Relay-ON-OFF-Module-/192106941494

    buBild accordingly and place in a project box with a push button on the project box also.

    Can anyone see any issues with this?

    any alternatives?

    The Ebay timer pcb will do fine, giving you a time range you need, if you just want to put the light on and off manually then all you need is a 12V 5amp psu and a switch.

    Thank you,

    it needs to be on a timer, so soon as a momentary PTM switch is pressed the timer starts.
