1000W Simple PA Amplifier

[tinitus]

looks like 8ohm to me ?

These performance data are much more than conservative... +/- 110 are over than 1.2-1.3 KW @ 4 ohm

because in reality, there are losses (in form of heat) from transformer and from the amplifier device. 😀

Here's the file for BA1200 Protect using NE555 IC....

Hello Sir Wiljj78... I have only 24volts coil supply of my available relay same type with this. Can u help me with what to change in parts for this protect?


Many thanks

Protect from post #28 can work with 24V without any change.

What is the maximum supply voltage for your version of the 555 timer chip?
All my datasheets show Vsupply <= 18Vdc

With transistor add to NE555 out any relay voltage can be use.

Apex,
I do not understand you reply.

Apex,

Supply voltage for NE555 is 5-15V

Hello Sir Wiljj78.... can you share for the PCB of this not mirrored. I will use for tonner transfer.

Thanks & Regards

Apex, are you expecting Boss to create a new LV supply from his 24Vdc supply, to power the timer chip?
Looks like you need to show Boss how.

No, I expect from boss to made descrite circuit (without NE555) with 24V relay.

how much DC will it accept ?

is that adjustable ?

Use DC voltage for protect same as ralay voltage or higher and add resistor in series with relay or use 2 relays in series with double DC voltage.

 

[tinitus]

ahh, no, I meant how much DC on speaker out, before it shuts down ?

about +/-1V

You can use this simple DC protection with 40A relay (12V for car)

hello sir i made this protect but how to test that it is working or not please help me. . .
