What range of current and voltage are you talking about.Originally posted by garyp@Mar 20 2006, 10:19 PM
does anyone know of a good over current/over voltage protection circuit i can add to a power supply.

i've got a 14v and about 0.25 - 1AOriginally posted by windoze killa@Mar 20 2006, 06:25 AM

i have just added a crowbar to my circuit but i am having a problem. when i turn the power on the initial surge is tripping the protection circuit. i think i need some kind of soft start circuit as i have proved that if i apply the voltage gradually it doesn't trip.Originally posted by windoze killa@Mar 23 2006, 04:30 PM
Do a search for crowbar protection.

You could try an inductor in series with the O/P line and capacitor to ground prior to the crowbar. This should remove any spikes or sudden changes.Originally posted by garyp@Mar 24 2006, 11:44 AM
