I have yet to use it extensively, but ran it through its paces the other night and found the features worked pretty much as expected. I especially like the programable memories, so I can set it up for different applications, and just tap the memory button and be ready to go. The over voltage and over current protections work well, as do the constant current and voltage functions. I do find the fine adjust a little odd, but that seems par for the course with these supplies. Finally, the ability to switch off the output and adjust the voltage and current with the output off is quite nice. FWIW, I've been doing electronics as a hobby and profession for pushing 50 years now. ### ⭐⭐⭐⭐⭐ Excellent power supply *by S***A on August 28, 2024* Very easy to use, accurate and reliable. If you look at forums this model comes highly recommended; such a high value product at this price point. Being a linear power supply it's a little wasteful, but I haven't noticed an excessive amount of heat, and while I haven't observed it myself, the waveform is said to have low ripple. If I needed another supply I would buy another without hesitation. ### ⭐⭐⭐⭐⭐ I love these *by O***A on October 22, 2024* I have a bunch of these and they work absolutely great. One of them has been running 24/7 for probably 2 years now. There are no power spikes if you use the output on/off button, the only way to get a small spike is to cut the mains power while the output is enabled but you're not supposed to do that anyway. I very much prefer these over switch-mode supplies because the output is extremely clean. The voltage and current settings and display are very accurate. I use these all the time and I bought my first one 4 years ago; I have both KA3005D and KA3005P (programmable) models and I've used to software to script one of them for automated testing. I did have an issue at one point where I needed customer support and both Korad and the seller (SRA) have been absolutely great with their support which is really important to me and I would say they went above and beyond. I had originally considered buying a "fancy" bench-top dual supply but decided that for the same money I can get 3 of these and that turned out to be a very good decision. My priority is to never get into a situation where I needed another power supply and not have one. I have 6 of them permanently as part of my work bench and a few more to move around where needed. If for some reason I needed another one I would buy this one again, no question. ## Frequently Bought Together - KORAD KA3005D - Precision Variable Adjustable 30V, 5A DC Linear Power Supply Digital Regulated Lab Grade… - Sumnacon 39 Inch Multimeter Test Lead Set - 5 Pcs Stackable Banana Plug to Test Hook Wire Cable Kit with Protective, Flexible Wire Leads for Electrical Testing 500V/5A - Sumnacon Multimeter Banana Plug to Crocodile Alligator Clip Test Probe, 5PCS 4mm Stackable Colorful Silicone Banana Plug to Alligator Clip Test Probe Lead Wire Cable 1M --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/6579220-ka3005d](https://www.desertcart.pl/products/6579220-ka3005d) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-06-16*
