hi exflaco
what is the gate resistor value for IRF640N in IRS900D ?
thanks

 

[Hadighorbani]

ok
no problem my friend
i think i used 1n5819
it is good to me for using 1n4148
i need realy OCP for this amp
i must creat that

 

[Hadighorbani]

i think sir manoj amp is best amp until today in all diy class D amps
i mean AUd600 is the best until today
thanks again sir manoj

progres in this project is 80%
have nice time

thanks again sir manoj

I also think so. Thanks to Manoj for sharing.

 

[kirubakaran]

want a clipping/ limmiter circuit

hi, manoj sir,
can u share your 1.6v ne5532 limitter schemantic and how is work.
thanks in advance

IRS900D dont work again and generate smoke when conecct input signal to car player

 

[exflaco]

Hadi very strange irs 900 its easy work may by a cut in the out the capacitor or the inductor very strange y use various ,vmos and inductors work chek the diodes tensions and the 12v auxiliar the negative its -vrail comon and the external wire gnd to te imput

what part did smoke ?is your connection correct? input ground to main ground?

its weird

Hi
10 ohm resistor and one 1n5819 burned
nearest the ir2110
above ir ic

Hi roben🙂
how can i know about cut in the out capasitor ?
i was used T106-2 and wire 0.8 mm and 43turn
i was used original lm317 board for 12 volts
i was used another power source for 12 volt board and my negative amp power not conected to lm317 negative power and not common
i dont conect my input gnd to out put or power gnd
please show to me on a picture
thanks

Hadi the schm irs 3000 chek the same conections irs900 minus ocp and minus totempole

 

[exflaco]

Hadi Chek post 3250 from Irvynejay its correct ,the same irs900 conections.

@Hadighorbani
you used 1n5819 in place of MUR120??? if so replace 1n5819 to mur120,,, irs900 freq is 250khz output filter should be around 47uh

 

[irvynejay]

Pls see file

and input ground should be connected to main ground

Hi
thanks sir manoj for your best quality amp

An externally hosted image should be here but it was not working when we last tested it.

Hello Hadi,
This Amp is nice and good, is it Aud600 by Manoj Sir??
Before going into this, I would like to make a budget, How much it costs you?

Regards,
Pravin

HI
i have IRFP250N
i can use this amps in 250KHZ only
about filter: i was used 25uH
i try with 47uH
thanks

thanks again
i was try VER2.0 of IRS900D but it not worked
when i connected in put ground to power ground the amp have above 10V DC in output
without that i had 5V DC in output
in ver 1 of this amp i had 5V dc in output too
