The one EEVblog tested in July failed, but apparently Korad has made improvements. See http://www.eevblog.com/forum/blog/eevblog-404-korad-psu-followup/** A: I ordered on Oct. 5, 2020. Mine appears to be another revision. The power board has one large cap, but newer transistors with a different layout and with surface mount components. The interface board appears to be another revision too. Both boards appear different than the original board and the revision shown on EEVBlog. Have yet to test this, though. **Q: it comes with the wires?** A: Yes it comes with hookup adapters banana plug to alligator clips and the power cord. **Q: Does this supply have programmable current limiting? Can you, for example, set a limit of 500mA?** A: It isn't really programmable by my definition, but it has a manual control that allows the course/fine limiting of current. (The knob on the right) It is also a push to hold your settings button. **Q: Does anyone know how to put this into constant current mode? I don't know if I'll ever actually use it this way but I am curious to see if it works.** A: Set what you want for the current. Then set your voltage 3 volts higher than what you require. It should go into constant current mode. If not, slowly increase the voltage until you go into constant current mode. The light next to CC should be lit. ## Frequently Bought Together - KORAD KD3005D - Precision Variable Adjustable 30V, 5A DC Linear Power Supply Digital Regulated Lab Grade… - BOJACK 1000 Pcs 25 Values Resistor Kit 1 Ohm-1M Ohm with 5% 1/4W Carbon Film Resistors Assortment --- ## 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.es/products/1298627-korad-kd3005d-precision-variable-adjustable-30v-5a-dc-linear-power](https://www.desertcart.es/products/1298627-korad-kd3005d-precision-variable-adjustable-30v-5a-dc-linear-power) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-07-07*
