Ah right. So I’m guessing the external board connected to the DPS3012 is just because the control unit isn’t big enough to contain the beefier components?
Yes, that will work, you can find 48 power supplies as well. I got a 150W 48V power supply from ebay for about $14. Works great as long as you don’t need more then 150W (which would be very hard to do with a 12A limit in a flashlight).
The Dell EPS-470 power supply previously mentioned in this thread is the same price, more powerful, and much better quality. I got mine on eBay for $24 shipped.
I ordered a DPS3012 from RD Tech last week. The discount is still available for the forum so get your orders in. You need to ask before you order. They have been very nice to deal with. Looking forward to putting it all together.
The DP shop now offers pre-made cases to fit, including a fan, rear switch, and banana connectors for input and output. No room to squeeze in an extra xt60 connector on the front though.
Well if you scavenge everything of course you can save $22. But most enclosures cost 9 or 10 plus shipping, and add a couple of bucks for the connections and switch, the couple of bucks left over then is getting you convenience (it all already fits, no cutting) and an enclosure of just the right size, if it's got everything you want. Also I think there's a discount available, just mention BLF as always. It won't be for everyone, but it's a pretty nice option. It's nice that they went with the full binding posts for connections.
