Hi Juan,
SP ERR LED works only when relay not energised (only 3 sec.)
When Q5(BS170) not conduct LED1 lit

oh .... ok, understand now 🙂, thank you, I will give a few more revisions of the layout, the PCB supply is quite big, I will see if I can reduce a bit more if not I do not mind this is one of my supply and is quite large = (grande) = large 😛
Best Regards

Hello mister Manoj I think the layout is almost done can you give a check when you get chance = "time" on the schematic you send me there is another option "Optional limiter" since my PCB is quite large I think I can find some space for that circuit what part number is the LDR mister Manoj ?
Best Regards
Juan

smps for classe d
I received my transformer pc40 49/32/19. can i have 1500w with him for my classe d amplifier without saturating ?
An externally hosted image should be here but it was not working when we last tested it.

Hi Mr.Manojtm.I plan to try one of your simple D amp design which using 74LS02.what"s the replacement for this ic series.its a rather hard to find.I've tried to upload the scheme but always failed.

good evening everyone this is my first post rode the IRS3000D amplifier with 2 pairs of IRFP4227 with supply +/- 80v but the IR2110 heats +/- 65 degrees this temperature is normal or giving to decrease this temperature at the IC required
Hi,
Using low Qg(20nC)& low Ciss with high fsw(400KHz) It will not heat up and Qg=70nC with 250KHz the same low temp (@40deg)
Qg=70nC ,Ciss=2300pf and fsw=300KHz IR2110 heat @45deg

Hi.
I have a question. Is oscilator 250khz works without MOSFETs?
When it gives to input signal 1 kHz sine wave, at 10 and 12 pin IR2110 have also 1kHz.
The frequency should be ~250khz. Why the oscillator does not work?

..during. my test I was exchanging speaker load between a real 6ohms speaker and a dummy 8ohms resistive load...but I haven't intentionally fired it up without speakers..but if kartinos finding is correct it should then survived..😉
BTW in the schematic I miss to include the 4k7 Gate to Source resistor and a 15k tap to +Vdd feeding the high side.
