DC Power Supply Variable, 0-120V 0-3A Adjustable Switching DC Regulated Bench Power Supply with High Precision 4-Digit LED Display, 5V/2A USB Port, Coarse and Fine Adjustment SPS-12003

Great psu. Cant quite get full current out most of the time(seems to top out at 2.5A at higher voltage), but for a cheap psu it is great. I find this works well for titanium anodizing, but it is slow on large pieces due to the high surface area to amperage ratio. It is super simple to use. Feels super light, but what can ya expect from a cheap psu.

This variable power supply is a game-changer for anyone working with electronics. Its flexibility allows precise voltage and current adjustments to suit various applications. Whether you're a hobbyist, technician, or engineer, its usefulness is undeniable. The intuitive controls make adjustments effortless, ensuring accuracy and reliability. Efficiency is at the heart of its design, minimizing energy waste while delivering stable power output. The sturdy build enhances durability, making it a long-term investment. Overload protection adds an extra layer of safety, preventing damage to your components. Compact yet powerful, it's perfect for any workspace. With consistent performance and user-friendly operation, this power supply is an essential tool for any electronics setup.

Decent for a basic power supply, but I can't stand the voltage adjustment. The coarse knob gets you somewhere in the right neighborhood, and then the fine dials it in. Both are ridiculously sensitive. I would prefer a digital adjustment knob. As far as performance, it seems to work well. I haven't tested more than a couple of amps so far, but it worked well for my needs. The device looks great, and has a bright screen.

Summary: This is the 3rd power supply I have bought since 2020. The first two were the same 30V/6A (180W), one blew out, and the other is still working. Wanted a bit more power when charging 12V AGM batteries, so ordered this unit, which is a 30V/10A (300W). Overall, very satisfied with the performance. Use-Cases: In addition to charging 12V AGM batteries, I use this bench top power supply to charge lithium batteries. Have a couple of Milwaukee M18 battery packs that are older, and sometimes drop below the point where the standard charger will recognize it, so after opening the case, I can individually charge the cells. I typically start with this charger, and then finish off the cells with an XTAR lithium battery charger. Sometimes the XTAR stops at 4.0-4.1V, so I use the power supply to drive it to 4.20V when top balancing the pack. Observations: This unit has a robust cooling fan, and when running at high current (above 5A) the fan kicks on. While the added noise might bother some, this is the purpose of the cooling, to keep the power supply within the allowed temperature range, which can lead to long term reliability. This 300W power supply's cooling fan is definitely moving way more air volume than the 180W one. Selecting this one was easy because it was the #1 rated offering in "Lab Power Supplies", with over 1000 ratings/reviews. Recommendation: Last time I researched power supplies was 2021, so I spent an hour looking at a bunch of different options in the $50-200 range. I looked at a couple of dual units, essentially two of these in one, with the ability to parallel or series the output, but decided against those offerings which were in the $150 price range (3x the cost). The same can be done manually (with the requisite knowledge) with two individual units). In general, if you buy a higher rated supply, and run it at half power, it should last longer than a smaller unit running at full power (all the time). Pros: Jesverty is a specialty power supply manufacturer, many with great ratings/reviews; cost is comparable to similar offerings. Cons: None for now. Conclusion: At $50 for a 30/10A (300W) power supply, rating this 5-stars.

Knobs feel cheap but it’s accurate and works well, fan isn’t too loud and it’s lasted me a while under frequent use

Been runing for a few days and it works as expected. like most switch mode supplies ita RF noisy. But for testing stuff and charging batteries it works well.

Works as advertised. Allows to set both Vol and Amp to desired levels. In higher settings the coils will whine but it doesn't affect the operation. Good value for money.

Excelente!

まず製品が小さいのとデザインが良いですね。これと同じような金額？の製品だと電圧だけの表示だが、この製品は電流値と消費電力値も３つ全部がランダムで表示されること使い易い。そりゃあP＝I・R？だけど数値が一目りょう然なのは素晴らしいです。ワニ口クリップが付属しているのもメリットです。

After a year I can tell that this product still working very good

Never used a bench power supply before but this was easy to set up and use. Was able to power my Raspberry pi while flashing the firmware and was very handy for setting up my canbus while everything was on the bench. Great product well built very happy
