DC Power Supply, 0-30V 0-10A Adjustable Regulated Power Source, 110V Input, High Precision 4-Digit Display, Multiple Safety Protections, PC Software Control & Dual USB Ports

SOFTWARE DOWNLOAD LINK IS AT THE BEGINNING OF THE PRODUCT DESCRIPTION!! Note: this is not needed unless you want to control it from a PC. NOTE: The .rar file at that link has a long filename, as do the nested directories, which causes Windows problems (failed my first try due to these long filename paths). Windows error messages (or lack thereof) are useless (Windows fault!). SOLUTION: Unzip (7zip) the contents to your root drive, and/or drag out the folder "iPowerCtrlv___" to a higher level directory, or even your C: drive, and install from there. Then it worked a treat. Also had to reboot to recognize the device. Small and extremely functional, doesn't take over my workbench. Love the display: your choice of history graph (good for tracking charging), or large output V&A display. All needed values shown on display at all times: Set values (V & A), Present output (V & A), Limits (OVP & OCP), Watts, Mode (CV vs CC), Time, On/Off - all except total Ah. Output within 0.01V of my voltmeter. Buttons & knob are simple, but everything you need. 4 memory slots (knob to select). Software spartan, but functional - 10 hotkeys for V/A settings, 100 memories, output control, configurable graphs (with export). The ONLY thing missing on this is total Ah, and I wish the fan was a little quieter - it runs even if the output is off (no load). Oh - and would be nice if the power switch was in front for ease of access on a workbench. Kiprim also responded within 24 hours to my request for the download link - and NOW I notice it was already at the top of the Product Description <insert sheepish grin>. If you want a 30v/10A supply with more than just V/A/W displayed, this is the one to get - or spend a lot more. Will update if there's any change ...

Has worked great so far, I have used this for several small projects repairing things around the house and building a few little lights. It does everything I need and based on multi-meter testing seems accurate. worth it for the average home user.

Just received it today so I will update if anything changes. The fan...I don't why everyone says it's loud. I had a simpler power supply (LONGWEI K3010D) who's fan was much louder when running. This thing is quieter on high speed than that one on high! Absolutely love all the features!! The graphing is a fun gimmick. It would be great if you could scroll back and see the graph over time! The real star is the memory. You can set up charging parameters for batteries or other projects. Adjust the settings and compare output to trusted multimeters and then save and forget. Save the settings and be confident of the output after that. Simple and done once! The other interesting feature is the ability to turn it into a manual charger of sorts with adjustable voltage, current and time frames. Could be very useful if you want to bulk charge a battery, desulfate and then have it go into a soaking charge before shutting down automatically. I will definitely update if anything changes on this but so far this is a fantastic unit!

This is a good hobby power supply but it did not work for my application due to the very slow ramp up time. I'm using 5v and you can visually watch it slowly ramping up over more than a second. That is outside the USB spec and will make some USB devices fail to connect.

The Programmable DC Power Supply (0-30V, 0-10A) is a versatile tool that’s perfect for anyone who needs precise control over their power output. Whether you're tinkering with electronics, testing circuits, or just need a reliable power source, this unit delivers with high precision, thanks to its 4-digit display. The multiple protection features give you peace of mind, knowing that your projects are safe from overvoltage, overcurrent, and overheating. Plus, the included PC software and USB charging capability add extra convenience, making it easy to program and monitor your power supply directly from your computer. It’s a solid piece of kit for any serious DIYer or professional working with DC power.

Perfect for any hobbyist electrical engineer or even professional. I've had for several months now and its definitely worth the money. The accuracy has held up over time as well and I really appreciate the charts on the front. It's not too heavy and doesn't take up as much room as most of the other power supplies I've used. I mostly use it for 24v and 12v devices during product development and have had no issues so far.

Fantastic instrument for this price! Having the live screen is an absolute must to monitor trends, buying anything without the screen would greatly limit the power supply's usefulness.

The Quality Control is terrible. Bought two times, two returns. First time works for around 3-5 mins without loading, loud bang and device is dead. Try to replace fuse, no joy. Second time - works for 9 mins with test load 12V 1.5 Amps (LED stripe), loud bang and heavy smoke out from device. It still operating, but seems that issue with cooler, which was melted inside the box and produced a heavy smoke. Just for fun will try to order third time. P.S. Third time - 2-3 mins of work and silently became dead again without any load. THREE TIMES, CARL!

Ich habe das Netzteil noch nicht oft genutzt, aber wollte es unbedingt haben. Bisher bin ich mit dem Kauf sehr zufrieden. Spannung und Strom lassen sich einfach und genau einstellen und die Anzeige ist gut lesbar. Das Teil macht einen soliden Eindruck und arbeitet zuverlässig. Die Bedienung ist insgesamt unkompliziert und nach kurzer Zeit selbsterklärende. Für den Preis bekommt man ein leistungsfähiges Labornetzteil, das genau das macht, was es soll. Ich würde es wieder kaufen.

No soy un profesional de la electrónica, pero llevo años usando esta fuente para mis proyectos y para probar pequeños circuitos y sigue funcionando perfectamente, de vez en cuando voy midiendo el voltaje y el amperaje y debo decir que es bastante precisa. Para buscarle algún defecto, es un poco ruidosa, pero, para un uso ocasional, se puede soportar sin problema. En definitiva una buena fuente para aficionados y oara pequeños proyectos.

Belle alimentation pilotable et programmable même via PC. Elle est petite, pas lourde, mignonne et précise. Pour le prix c’est incroyable. Avec un petit écran qui montre de façon graphique ou numérique les infos. Juste pour info, pour le logiciel, il faut prendre le dernier logiciel pour que sa fonctionne et s’installe correctement. Le lien de téléchargement ce trouve sur la page du produit. Et après tout fonctionne comme une horloge.

Bien précise et stabil.....Nickel

Bought as an upgrade from the internet auction special analog power supplies, as that one was frustrating when the input would drift. It's precise, easy to use (if not intuitive), the software is windows only and is mostly just a display, but it supports pyvisa so you can write your own python code to talk to it and do logging. Fan is noisy if you're pulling more than 50w, so bear that in mind, I might swap mine for a noctua or something similar in future. The quality inside is amazing, selastic on every connector, beefy high-rating capacitors, nice little serial comms board, and the screen print markings on the pcb. seem to indicate this is an owon product on the inside. It's not a lab power supply, don't expect it to be, it's noisy on the output and the polling rate isn't massively quick, about every quarter second from what I can tell. It's not priced like a lab supply though! Perfect for charging batteries, a bit of custom code logging, testing RC equipment, emulating other power supplies, and running small to medium electronics projects.
