+title: "Bought my first "bench" power supply 😁"
+url: "https://images2.imgbox.com/f3/83/VUCfUxRP_o.jpg"
+body: """
I’ve been in need of a bench supply for a while, up to this point I’ve been using little buck/boost boards with a multimeter to get the voltage I want when working on a project. The limitations of that started to show though, so I was after a more ideal solution.\n
\n
After spending a while looking at various power supplies, I happened to come across this tiny adjustable supply. After binging a bunch of videos on it, I decided it’ll do, especially compared to the absolutely chonky big alternatives.\n
\n
Right out the gate, the aluminium casing feels amazing, but they could do with a bit of a stronger adhesive holding the glass screen cover in-place 🤦\u{200D}♂️ I’m personally not too bothered by this, but it doesn’t set a good first impression IMO\n
\n
\n
\n
A few seconds after pressing the glass back into place, the opposite end of the glass popped loose. At least I now know there are screws hidden under here if I ever decide to open this in future 💭\n
\n
\n
\n
Aside from that, it has pretty reasonable specs for the size:\n
\n
- Dual input, either AC (mickey ears plug) or DC 7-28v (XT60)\n
- 30V 10A (max output 200W on DC, max 100W on AC)\n
- Minimum output 1v 500mA\n
- 65W USB PD output (handy for the Pinecil I recently ordered to replace my old iron 😁)\n
- 200x200 IPS display\n
- AC input uses GaN parts\n
\n
When watching the videos a few people complained about the absence of an XT60 to banana jack. This may have changed at some point, as one came with mine\n
\n
\n
\n
The internal AC converter appears to supply 19V into the unit, which you can use via the XT60 connector at the rear. Not sure if intentional or not, but pretty neat nonetheless - as long as you dont accidentally leave a lipo plugged in there 😳\n
\n
I’m not sure if its worth the price tag ($60-120 depending on where you look) when you can get a RuiDeng clone for under $30. I mainly jumped for this because of the size, integrated AC input, and that 65W USB-C. Voltage ripple is a little concern at lower voltages where some components may not be so forgiving…\n
\n
Happy with the purchase so far though, can’t wait to start using this for projects!

This decade old electric cooler box gave up the ghost around 2 years ago, with the indoor outlet plug no longer working. The independent 12v input was still operational, so I kept it with the intention of *eventually* fixing it…\n
\n
And two years later, this is the eventually 😅. The integrated 10v ~45w unit had failed short on the primary side, with a burnt out Y-capacitor and some fried zeners. I started removing bits from the board to try and find all the broken components… but ended up letting out the magic smoke in the process, oops!\n
\n
I set out looking for a new power supply, and came across a 12v 45w unit from Meanwell. It was actually smaller than the cooler’s original power supply too, meaning more internal space to use later 🤫\n
\n
Spoiler\n
\n
After searching for a distributor that was actually willing to ship it to a home address, I ordered, and boom:\n
\n
\n
\n
It’s so tiny compared to the original.\n
\n
Next I installed an Arduino Nano to control the TEC/peltier module & fan via a cheap LED repeater. I was hoping to reuse the internal temperature sensors, but left them disconnected for now\n
\n
\n
\n
After hours writing the arduino code, I finally got it into a usable state. There were issues with brownouts rebooting the Arduino, however with the Meanwell supply in-circuit those mysteriously stopped.\n
\n
There are 3 power modes now for the module: 30W, 40W and 50W - with the first two using PWM, and the last one giving it all the beans. I wanted to PWM control the fan too, but decided against it since it sounded absolutely terrible at whatever PWM frequency the Nano is using.\n
\n
It powers on to 40W by default, which is under the 45W max rating of the PSU.\n
\n
Everything looks good so far running from the bench supply:\n
\n
\n
\n
Now all that was left was to connect the internal supply, and the 12v vehicle input. I was actually supposed to use JST connectors for the Meanwell psu, but didn’t have anything on hand - so improvised with crimping spade terminals and friction fitting those on\n
\n
\n
\n
And the moment of truth. Up until this point I hadn’t actually checked if the replacement psu was working or not\n
\n
\n
\n
Looking good! I don’t really like the LEDs though, so might do something about those in future.\n
\n
You might be wondering how exactly I change the power settings… well since the manufacturer decided it was good enough to shove all the cables in the back, I did the same with a pushbutton 🤫\n
\n

Glad to have the electric cooler working again though, feels nice to save large things like this from going to the landfill and extend their life a bit. Excited to hear any thoughts and feedback!
