That one just needs some euro terminals and a few diodes. It was fully
functional before I stole the euro's out of it.
I'm keeping my other 4.
Just that one , I will swap parts or something for it.

So an early version had a whole nano (usb spacing?) Which one has the integrated ATmega328 dip? The SMD version, might be hard on my old hands.

I've never had time to get the SMD version completely debugged yet. The through hole versions are working well. There is two versions with Atmega328 DIP. One has solid state relays, one has mechanical.

I also have the small PCB's that make any of the mechanical relays solid state.
I don't really need them because I have two of the newest PCB's (All SS).

Hello
greetings nice protection can this solid state relays work at 40 amperes ac
speaker out current i want to build the protection specially the overload part
for my PA amplifier
warm regards

I haven't tested them at that current but the mosfets are rated for 180 amps continuous.

Hello jwilhelm
greetings thanks for replying i will try your mosfet relay waiting
for ASSR-V621-002E as in my city some components are hard
to get as i cant make the 21 century protection
so i will try a cheap DC and overload short circuit protection
as you can see these cheap mechanical relays shown on pcb
have to be replaced with your SS relays even tauros ACS712
overload protection works
warm regards

Infineon IPB025N-10N3 are rated for 100V and 180A. https://www.infineon.com/dgdl/Infin...n.pdf?fileId=db3a30431ce5fb52011d1ab1d9d51349
I think I emailed you one. 3.5 and 3.6 are the same. I had two caps backwards in 3.5.
Basic idea for rail shutdown
Basic circuit I'm looking at to use for rail shutdown. Probably will design the opamp outputs to take the gates beyond ground by 5-10v for improved turn off. Just an idea, I'm kicking around.

You can drive the rail fets directly with a ASSR-V622-302E. It has a quick off circuit on board and will optically isolate the protection board from the rails. I've done this in my protected supply. It's working perfectly in testing, but hasn't gone into service yet.
Hello jwilhelm
Yes I have thought about that also. Most of my new amp designs, have separate front and OPS rails, something else to consider. Will this be part of your smd redesign? And thanks for the files, got them ok!

This can already be run from the existing boards. Either switch them on with the power relay control or use one of the extra outputs and modefy the code to run it.
