4 Tap DC Converter/Isolator Mockup Pedal - Arriving Soon!

It seems like it's one of those snap together (or possibly even glued) assemblies that you basically have to destroy to open up.

Maybe I’ll order a broken one from Amazon and post pics.

16 pin IC is DF6109A
8 pin ICs are AO4606

Transformer has no identifiable markings.

So what exactly does this too us? Surely you can’t put one of these on each daisy chain plug to isolate it right? If so that’s a clever idea. Wonder what the usb one does

Figuring out the specs on the converters is kind of going over my head. Can anyone point me toward the right Mouser converter for what I'm trying to do, which is:

9V OneSpot wall wart (1500 mA) > 4 Tap > 9V outs (maybe 250 mA, something around there)

Hex standoffs. You can either mount it to the enclosure with screws, or if you'd prefer a flush exterior with no mounting hardware you can float it between two sets like this:

(Different PCB, same concept)
View attachment 68899

By "float," do you mean that instead of external screws, the PCB is held in place by the pressure of the screwed on backplate against the standoffs? Is there a size that works best with a 1590A?

Those isolated DC-DC converters look like they take 5v input. If you have a 5v power supply, couldn't the 5v LDO and rectifier circuit be bypassed?

What would be a super nice companion to this is something like those USB battery packs meant to charge your phone or other devices. I.e., something that accommodates a number of 18650 or 21700 lithium-ion cells, and includes a mains-power-based charging circuit (a charging circuit that is robust enough to allow the battery pack to be used as a supply while it's charging). And some way to indicate remaining battery charge.

The use-case is to have all the goodness of individual high-current, isolated DC supplies for your pedals, and modern lithium-ion batteries as the source, as well as the ability to plug the power supply into AC mains in case you forgot to charge the batteries.

Essentially, a UPS (uninterruptable power supply) for your pedals.

@MattG I’ve also wondered how you could integrate those usb phone battery packs to power pedals.

Absolutely, there are 9V versions as well.

The regulator and rectifier (and 5V converters instead of 9V) are solely for the "universal" power supply capability.

It can (and probably should) be made much simpler and efficient by dropping that whole section.

Not sure If we can post links so I’ll post a picture of a one control DC Porter Plexi that appears to run off the mobile phone chargers.These are just screen shots
