after heating, temperature of FET about 55*C and it cool down fast so I think when we heating again after 1-2 mins it OK ^^
I think you can DIY 1 heater like me and forget the module you buy on EBAY ^^
Thank for your advice,
I'm check again, measuring direct input IH, the curent is 14A
Temperature of transistors is under 60*C I think is not too high because we using IH with shot time.
Hi everybody,
I make a new circuit and have some testing the position of the vap in heater.
I want to know the position of the vap in your heater in any case, 1 or 2 and what the best case ? thank you for reading ^^
Case 1 the vap tip inside the coil.
Case 2 the vap tip outside the coil.
I think the issue is the quality of ZVS. You need to test the temperature of ZVS when it working. If anything on the board when heating you touch feeling too hot (about 70 *C) that is not good
