Ready-to-Run (RTR) SSR DC Speaker Protection and Delay GB

[xrk971]

I am looking forward to hearing everyone’s reaction and feedback on these units once you get to use them.

I have shipped everyone’s order today except for Gary’s in order to consolidate some shipment of other items at his request.

Thanks for the update X, out of interest how many SSR boards does that leave you to sell - might get some more for all the planned projects I have stacked up for next year and beyond, but don't tell my wife!

 

[xrk971]

There’s 34 left but if I subtract a set for myself, Jhofland, JPS64 that’s 28 left. We can order another set of demand calls for it.

 

[gary s]

OK, thanks X, will work out what I need and check your Etsy store.

Thoughts on using a terminal like this?
1905214 Phoenix Contact | Mouser

 

[xrk971]

That Phoenix connector is too bulky to fit there, moreover, the pitch is incorrect as positive and negative terminal are side by side and narrow. I highly suggest you use crimp terminals either spades or Molex quick connect as designed. Screw terminals are really not ideal for the best connection. Get a crimper tool and use Faston female spade connectors with male Faston tabs. That’s how many amps are wired anyways.

While on the topic of PCB mount high current connectors, any thoughts on the ones Keystone makes? They are a brass plate with PCB pins, and a screw up top. I think some of the PCBs on diyaudiostore use them. Are they good, or would you avoid them too?

Something like these?

I know it's OT, but I thought I'll risk it... Sorry.

Those can work but note the tight clearance of the positive and negative. The screw might short out both sides.

I wasn't actually thinking of them in the context of this PCB. I was thinking generally, for future projects.

 

[xrk971]

Oh, then that’s fine then. There is also version with 4 prongs down and screw facing up. Those are nice and easy to use.

Thanks X

 

[gary s]

Now you just need to find some power amps to put them in, I suppose you have a few sitting around waiting for that protection.

 

[Vunce]

Haha! Yes I do Gary.
Hopefully by end of night I’ll have a pair mounted in their new home

 

[gary s]
