IR2113 blowing ! help needed...

[savu]

drive them trough 10 ohm resistors or smaller.
for me it seems not that smart to use dead time before the IR chip. (extra parts)

Dear Sir Alex,
Could you sent me the schematic & PCB your Project please?
I'am very interested with classd amp.
My email: hari_wibowo_jmb@yahoo.com

Thankyou for your cheapness.

HI
greetings at last managed to make amp work using IRFN250 supply
voltage 50 0 50 dc just some pics
warm regards

nice work Andrew!

Where did you get the files for DIY construction?...wish I can have it too..

Regards!

[andrewlebon]

Hi Abeteer
greetings all files can be found onthis ucd thread just stick TO orignal pcb by
egtagle THE SMALLER PCB you wont go wrong if you start your construction in a
logical way i found out the hard way see when i started this thread and when i managed
finally to make it work but better late than never check all parts before soldering and for shorts on copper side correct orientation of caps and DIODES
warm regards

you won't get pcb, schematic is on my site, where you can download it

Hi Luka!

I saw your work on Elektor mains delay circuit, I built the same using the PCB lay from Elektor but I could not properly fit those bigger wirewounds so it looks like "out of nowhere" build I wonder if you have done a modified lay-out on your PCB, the wirewounds was nicely arranged. Will you be sharing the files?

Regards!

I'm also sorry for off topic, but to answer.. yes, I did my own board from the begining, and the reason why everything just fits
I will look what I have, you'll get the PCB from my site, I guess I didn't put it up there yet, so I'll look into it and make sure, it will be there in a day or two (not at home today)

There is one thing, I need those big resistors only once, when I guess I wanted to power dead short, and only that time those resistors got hot, there was about 230w on them for few seconds, 2w would in any other situation work just fine

[abeteer]

Thank you Luka,
I will be checking it on your site.
BTW on my built I find-out the relay line coil (supply) was warming up, other than that it works just fine. I am also using a 24V 10ampere relay on 220V AC mains.
