Review: Quality and - Not received as mentioned. Received old version. Working ok ok Review: Software not working - I found some software on github that works. The storage that comes with it is national instruments LabVIEW but made into an executable. I’ve done a lot of labview for work awhile back. I couldn’t get the step functions working in a way that wasn’t a pain. It work save it. I can’t edit the file easily. It gives me this error so it’ll take you hours to actually make useful step functions. I need this to work for engineering test. I also downloaded the latest NI runtime files. Still didn’t work. So then I found some open source software someone made on github. Please send that guy a coffee if you download it. Works great. Other than the software the power supply is amazing. It is noisey but I work in a lab don’t care. It is heavy also. Very heavy. Nice small size compared to my other power supplies. I just can’t give. A good review when I only bought it for the software use. I don’t have time to write my own code. ## 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. - ◆ PROGRAMMABLE CONTROL - USB & RS232 ports for remote control of the power supply. Software is included - ◆ WHAT YOU GET - 1 x Korad KA3005P Power supply , 1 x power cord , 1x Set of 5 Amp test leads, 1 x User manual ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0085QLNFM | | Brand | KORAD | | Built-In Media | 1 set of 5 Amp Test Lead, CD containing Remote Control software, KA3005P Power Supply, Power Cord, USB Cord, User Manual | | Compatible Devices | Various electronic devices and equipment | | Compatible devices | Various electronic devices and equipment | | Connector Quantity | 6 | | Connector Type Used on Cable | usb | | Connector type | usb | | Cooling Method | Air | | Current Rating | 5 Amps | | Customer Reviews | 4.4 out of 5 stars 221 Reviews | | Form Factor | ATX | | Form factor | ATX | | Global Trade Identification Number | 00022099136453 | | Item Dimensions | 35.6 x 25.4 x 25.4 centimeters | | Item Type Name | Power Supply | | Item Weight | 4.08 kg | | Manufacturer | Korad | | Maximum Input Voltage | 220 Volts | | Mfr Part Number | KA3005P | | Minimum Input Voltage | 110 Volts | | Model Name | KA3005P | | Model Number | KA3005P | | Model name | KA3005P | | Number of Fans | 1 | | Output Wattage | 300 Watts | | Output wattage | 300 Watts | | Power Supply Design | Full Modular | | System Bus Connector Type | ATX | | UPC | 022099136453 022099136354 | | Unit Count | 1 Count | | Upper Temperature Rating | 115 Degrees Fahrenheit | | Wattage | 150 watts | ## Product Details - **Brand:** KORAD - **Colour:** black - **Item weight:** 9 Pounds - **Connector type:** usb - **Input voltage:** 1.1E+2 Volts ## Images ![KA3005P - Programmable Precision Variable Adjustable 30V, 5A DC Linear Power Supply Digital Regulated Lab Grade… - Image 1](https://m.media-amazon.com/images/I/71fSoVc3+qL.jpg) ## Questions & Answers **Q: Is this the "fixed" model? 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. ## Customer Reviews ### ⭐⭐⭐ Quality and *by G***G on 9 October 2025* Not received as mentioned. Received old version.

It simply does not provide the power when under load. The voltage sags and drops dramatically. If I set the output to 12.8V at 5 amps, I expect it to give me that voltage. What I get is 7.7V under load, and I get under voltage alarms from the devices I am testing. Even when I increase the voltage, it sags. No good to me. It is going back. ## Frequently Bought Together - KORAD KA3005P - Programmable Precision Variable Adjustable 30V, 5A DC Linear Power Supply Digital Regulated Lab Grade… - Micsoa Multimeter Leads - Alligator to Banana Plugs & Mini Hooks Set (3 Pair) - WGGE WG-026 10 Pieces and 5 Colors Test Lead Set & Alligator Clips,20.5 inches / 22 AWG Copper Wire.
