Hypex UcD400HG+ SMPS400 monoblocks

[BlackBushBaby]

Hello everyone.

I currently use these monoblocks that I built about 2 years ago. It is the UCD400HG with HxR and SMPS400 powersupplies. I have been very pleased with these, but would like to add a 12V trigger circuit to it.

Do any of the more experience members here have some tips or suggestions regarding this?

Also comments about the layout is welcome.

Reading a bit more about it it seems that the triggers might still trip the power fuse if all all 3 monoblocks activate at the same time.
Seems like the solution to this might be more complicated than I expected.
I assume a master/slave switch with delay might be a good alternative.
