Dc-dc converters? Surely. I know RS Do.
Radio Shack? You guys still have those down under?
Mouser and Digikey only sell professional and technically sound stuff with reliable data sheets. Probably developed specifically for the soft audio market.
This seems like a garage setup with little or no tech info.

A quick look at Mouser. They don't have THAT brand, but after narrowing it down from 88,000 DC/DC converters to the specs on your sample:
2 Output 15 W 18 V to 36 V 15 V - 15 V Isolated DC/DC Converters | Mouser
Some as low as $20. Your Godsend brand seemed to be selling for $34 or so?
2 Output 15 W 18 V to 36 V 15 V - 15 V Isolated DC/DC Converters | Mouser

Thank you!Terrific answer unlike previous member. Exactly what I was looking for. Obviously my serching capabilities not remotely as good as yours.

Well you asked for a specific brand/type whether Mouser or Digikey were selling those. If you had made it clear that you really wanted 'a' DC DC converter for a specific value, you'd had your answer 1 hr ago.

Thank you
I find it helps to not be overly specific at first doing a search there.
If I knew options I wouldn’t have to ask. 🙂
I think it was originally Radio Spares? But now just RS. They're UK based I think, but have global reach.Radio Shack? You guys still have those down under?

For future reference, at Mouser - and digikey et al are similar - I entered DC/DC converters in the search, and up comes a page of DC/DC converters, 89,000 of them.
It optioned me two groups ; Isolated and non-isolated. I chose the larger group. (I went back and checked the other group and found nothing I wanted)
Below the top is a bunch of search parameters, among them number of outputs - I chose 2 - and input voltage - I chose 18-36 from your example. There was also a selection of output voltages for each channel. I chose 15v for each.
At this point I click APPLY FILTERS button to lock in my choices so far. And when I do that I always also check the little box that says "in stock" as I don't want to wait. That reduced the selection to 123 choices.
SO your example said 12 watts, I see I chose 15 watts, and so one more round, and I linked that result of 14 choices. I think at 12w there was only one choice.

Appreciate a lesson. Thank you!
