Popular Applications Automatic Testing in the Production Line School Laboratory Repairing Research & Development Quality Control Aging Test Complete digital control with memory storage 4-digit display Intelligent temperature-controlled fan Compact design 10 mV /1 mA resolution Low noise and ripple Review: Very nice bench supply. - This is a very nice and not terribly expensive single output power supply. 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. Review: Excellent power supply - 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. ## Features - ◆ HIGH PRECISION INSTRUMENT WITH MANY UNIQUE FEATURES - Very Easy setup with a rapid adjustment knob. There are buttons to switch to course or fine adjustment and a button to switch to voltage or current selection. The input voltage is switchable between 110/220 Volts for use in all countries. It has 4 Memory Recall buttons so you can save time setting up the supply to your required conditions. - ◆ 4 DIGITS READINGS WITH BACK-LIT LED DISPLAY - With a 0.001V and 0.001A resolution, 4 digits provide more accurate and clearer visible readout for the voltage and current values with only 1 knob, extremely durable and easily visible even in low-light usage, meeting the needs of most people, ideal for business, small labs or the hobbyist at home. - ◆ HIGH-QUALITY WITH ESSENTIAL SAFETY - Grounding wire, thermal protection, voltage and current overload and short-circuit protection ensure the safety. The built-in quiet variable fan reduces the operational noise and prolongs the life of product. There is a load on and off button so you can safely connect your load to the supply. There is also a lock button to prevent accidental changes. - ◆ CONSTANT VOLTAGE & CURRENT OPERATION MODE - Easy to dial in the desired voltage with the encoded-controlled adjustment knob and then you choose the mode with one of the constant buttons. - ◆ WHAT YOU GET - 1 x Korad KA3005D Power supply , 1 x power cord , 1x Set of 5 Amp test leads, 1 x User manual ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0084JFWNY | | Amperage | 5 Amps | | Best Sellers Rank | #61,496 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #38 in Lab Power Supplies #82 in Life Science Supplies | | Brand | KORAD | | Built-In Media | KA3005D Power Supply | | Color | White | | Connector Type | Barrel Connector | | Connector Type Used on Cable | Barrel Connector | | Customer Reviews | 4.5 out of 5 stars 226 Reviews | | Enclosure Material | Metal, Plastic | | Form Factor | benchtop | | Global Trade Identification Number | 00022099136316 | | Input Voltage | 220 Volts | | Item Dimensions | 13 x 10 x 8 inches | | Item Type Name | Power Supply | | Item Weight | 10 Pounds | | Manufacturer | Korad Technology | | Material | Metal, Plastic | | Mfr Part Number | KA3005D | | Model Number | KA3005D | | Output Current | 5 Amps | | Output Voltage | 30 Volts (DC) | | Output Wattage | 150 Watts | | Specification Met | certified frustration-free | | UPC | 022099136316 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** KORAD - **Color:** White - **Connector Type:** Barrel Connector - **Item Weight:** 10 Pounds - **Material:** Metal, Plastic ## Images ![KORAD KA3005D - Precision Variable Adjustable 30V, 5A DC Linear Power Supply Digital Regulated Lab Grade… - Image 1](https://m.media-amazon.com/images/I/71MKjLqF4vL.jpg) ![KORAD KA3005D - Precision Variable Adjustable 30V, 5A DC Linear Power Supply Digital Regulated Lab Grade… - Image 2](https://m.media-amazon.com/images/I/81x3EfFLqRL.jpg) ![KORAD KA3005D - Precision Variable Adjustable 30V, 5A DC Linear Power Supply Digital Regulated Lab Grade… - Image 3](https://m.media-amazon.com/images/I/31OnI5IxSDL.jpg) ![KORAD KA3005D - Precision Variable Adjustable 30V, 5A DC Linear Power Supply Digital Regulated Lab Grade… - Image 4](https://m.media-amazon.com/images/I/81an3lQ48AL.jpg) ![KORAD KA3005D - Precision Variable Adjustable 30V, 5A DC Linear Power Supply Digital Regulated Lab Grade… - Image 5](https://m.media-amazon.com/images/I/71vtfvqjWdL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: What is the minimum increment can it adjust the output voltage?** A: The Output can be adjusted.

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.

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.be/products/6579220-korad-ka3005d-precision-variable-adjustable-30v-5a-dc-linear-power](https://www.desertcart.be/products/6579220-korad-ka3005d-precision-variable-adjustable-30v-5a-dc-linear-power) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-18*
