New Product from Holiday Lighting: 4 Port Power Fan Out/Distribution Board

It's not designed for a particular enclosure because almost 100% of the time it will co-exist with a power supply in close proximity.
It has four mounting holes at the corners.
The LED displays are inexpensive and come in many colors. If you can wait 30 days, they are about $1 on aliexpress.

what box are these designed to mount into say like a ta-200 sort of box or?

And the little voltage display, available with the pre-order or have to find it someplace else?

I used double sided foam tape under the voltage readout but I also drilled small holes for tiny screws. No chance of the readout to pop off.

So... in case you were wondering about shorting the board out with those display screws you don't need to worry.
The top half of the board, top and bottom, is the positive power plane and is already tied together with lots of vias.
Just be careful not to get into the traces for the low amp connectors on the left hand side.
Looks Great.

It is a 1 in 4 out power distribution board.
You supply it with 12v or 5v and get 4 ports out to be used for injection.
I used several in my display to inject along a 5V pixel run.

So, the question is this...
What are you trying to protect?
A fuse is really a safety item designed to blow before your wires melt and perhaps start a fire.

The size of the fuse has nothing to do with the available load.
It has everything to do with the size wire you run between the load source and the item drawing power.

If you use a fuse with a rating that is higher than the amp rating of the wire connected to it, it does no good at all.

So, in our hobby, we use fuses to first keep a wire from turning red hot and melting.
Secondly, if something connected in the chain of power has a dead short, it can protect everything downstream of the fuse from experiencing the results of the short.
i.e. if you have four items connected to this breakout board and one of them experiences a short, the fuse on the breakout board will blow for that one connection, yet leave the other three up and running.

Question: Do you need another fuse between the PSU and your controller? I see some folks using these between the PSU and the controller (and between the PSU and this breakout board).

And what size fuse? The PSU is 29A PSU(150W). A 30A fuse then?

Technically, though, in this hobby/line of community service, I use fuses to protect my relays more than anything.
