I need help to get a circuit to work. I found a triac controlled circuit on the web but I can not get it to work.
I used a dimmer switch to control the current on a 220/24VAC
transformer that worked well but does not last. I replaced 3 dimmer
switches before I decided there must be a more reliable way and safer
way to cut foam. The circuit was used by a person that claims
he has been cutting foam with it for the last 15 years. here is the link: http://www.nsrca.org/technical/tip_tricks/foam_cutter/foam_cutting_power_supply.htm.
So I think it must work
but perhaps he did not include the correct circuit. I cannot get his
contact details to ask him.
please could someone put it in multisim and simulate it for me. please note that I am using a 24vac @ 10amp 50Hz and not 2 amp as in the circuit. I actually need between 4.5 and 5.5 amp to cut EPP foam
