Budget friendly adjustable bench Power supplies perfect for testing LED's and other uses!

Is the DPS5015 the highest power unit of this brand?
No DPS over 750W?

It is the highest at this point that I know of.

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?

Yeah, for that kind of amperage you need way better heat sinking then the self-contained display setup allows.

Thanks, suddenly all becomes clear. :slight_smile:

Would this be a good match for the DPS3012?

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.

Sadly I couldn’t find any this side of the pond. I did manage to find the Banggood supply much cheaper on eBay so that’s something.

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.

Some additional information about the buck/boost module I previously linked (#69):

Marty's Techno Blog Software Engineer - MingHe buck/boost converters – handy, if you’re careful!

Also called D3806/B3806/DPS3806. Advisable to disconnect the load on power down first to avoid voltage overshoots.

May also be found a tad cheaper if you look for “app only” deals.

Cheers ^:)

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.

Flintrock, I’m having problems finding it, do you mind linking me?

Edit: is it this one?

this

Yes, that is it, they have 2 versions, 1 for the small 5A and below power supplies and another for the larger 10A+ power supplies.

Meh, I spent $35 on the power supply, I’m going to have a hard time justifying $22 for the enclosure…

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.

Yeah, it’s a fair price probably. I’m just weird and like to splurge on some things and cheap out on others.

I agree, I would most likely have still built mine DIY even if this was out at the time. Things that don’t give me a tangible benefit are very hard for me to justify with my current balance of time vs money.

Now down the road things will most likely change some.

Is that case aluminium?

Anyone knows?

It appears to be aluminum.
