24V to 5V 10A 50W DC DC Converter Regulator Car Step Down Reducer 24V to 5V 10AMP Daygreen CE Certificated (WHL #46)

Alright, part two of the DC-DC converter tests that’ll lead to a small project. This time we got a 5V/10A converter from Daygreen, model number B10-1224-05, shipped together with the 12V/10A unit from WHL #44. This item was 2.41€ excluding shipping, as described in that blog post.

It’s a brick style unit as well, a tad smaller, but also has two mounting holes left and right which are flush with the case. Contrary to the more powerful 12V one, this is only a plastic case that was potted, but it has four screw terminals and therefore offers more flexibility when it comes to attaching your own wiring.

Overengineered parts from China aren’t really my cup of tea, but this is for an upcoming project with power-hungry, rotating AND rusty plates, so I figured I would use something up for the task…

…and I don’t think I paid that much of a premium for it. So today’s item is a step-down converter model “D121” rated 10 amps at 12V, with 15-32V input voltage. Price was 2.86€ at the time; contrary to the usual item on this site, this was without shipping cost. […]


250W DC-DC Boost Converter Adjustable 10A Step Up Constant Current Power Supply Module Led Driver For Arduino (WHL #21)

What do you do when none of your existing power supplies can provide enough power for some decent LED module? Yeah, right, you buy a bigger one!

So I did. I had some 100W/150W DC-DC converters laying around, but most of them cap at around 36V. And with the very nice Toshiba E-Core 92W LED module that wants 40V or more, that’s just not good enough (same goes for the popular 25W/50W/100W LED modules!). So the new one in my collection is this:

Some more shots:

I bought it on AliExpress back in mid-January for 4.31€ including shipping.

Tech specs are, according to the seller: 250W total output power (boost = step-up only), non-isolated output, input current 8A or 10A with additional heat sinking. […]
