The manual shows a series/parallel indicator LED's and different labeling for some buttons.** A: Yes, the picture is not accurate. On the right unit in the picture, the OVP LED = SER LED and the OCP LED = PARA LED on the actual unit.On the right unit again, the picture shows the OVP button and the OCP button. The OVP button has PARA/INDEP written above it and the OCP button has SER/INDEP written above it on the actual unit. The manual shows the PARA/INDEP and SER/INDEP labeling switched around, so even the manual is printed wrong! However, when dealing with electronics, I found datasheets and manuals to be incorrect a lot of times. It just shows that the engineers and technical writers don't hang out together nor the advertisers for that matter . Haha.Please also note that that the power suply is a KA3005D-3S, but the picture is of a KA3005D, so that's a third thing wrong!Good news is that the power supply works well, so I highly recommend it. **Q: I'm shipping this outside the US, I live in Qatar, where the mains are 240V, 50Hz. Will this work under these conditions?** A: I own one. Switch on back selects 110V/220V. Manual indicates 110V/120V/220V/230V, 50/60Hz. It should work fine. I'm very happy with mine. ## Customer Reviews ### ⭐⭐⭐⭐ Solid power supply, mostly idiot proof, some UI quirks. *by S***N on January 15, 2015* There's a review of the single-channel version of this power supply on Youtube where the reviewer runs the supply through all sorts of crazy stressful tests, such as using it as an arc welder (!). This thing is pretty robust. Ability to switch into parallel or serial modes with a pushbutton is really nice. The extra 5 volt output on top of the two main outputs is handy for hybrid analog/digital circuits, you can run positive and negative rails for audio and 5V for your digital.Some notes:Because the serial mode button is a long press of the over-current protect button, and OCP switches on the down-push of the button, if you want serial mode without OCP you need to turn OCP *on*, then long-press the button to turn it off and engage serial mode.The logic can be a little weird when driving non-resistive loads. I put it into 30 volts serial (60 volts between the outermost terminals) and hooked it up to a 22 millifarad power supply capacitor, turned it on, and it wouldn't charge the cap. I think the capacitor looked like a dead short, so it lowered the voltage to limit current, but then it stopped looking like a short and confused it or something. I charged the cap by setting the voltage low at first then gradually ramping it up till I got the full 60 volts out of it. When I lowered the supply voltage it didn't react too quickly, it was probably limiting the discharge of the capacitor through the power supply, so that's pretty good.I wired up 16 3-volt LEDs serially and put the power supply into 24 volts serial (48 volts total) with current limiting to the rating of the LEDs, no load resistor. The display didn't know what to make of it, the two sides of the power supply disagreed about how many volts they were pushing, but it drove the load fine.I set current limiting to 20mA and tried hooking up an led while the supply was hot. It fried the LED, so current limiting won't help you if you arc while hooking up your electrodes. ### ⭐⭐⭐⭐⭐ If you're looking for good bang for your buck... *by P***O on April 26, 2013* I'm a math teacher with a math degree and no formal EE training, but practicing electronics and design has become a hobby of mine. Most of what I know is from ocw/mit, eevblog (Dave, you're awesome!), and getting my hands dirty on breadboards. I've played guitar for over 20 years which quickly steered my interests in electronics to guitar effects circuits. Needless to say, I do a lot of playing around with op amps, so a dual supply was a must.When I was looking for a power supply, I didn't want top of the line because it wasn't in the budget and quite frankly, I just didn't need it, but I didn't want to see my money go to waste on a piece of junk either, which can easily happen when you're looking to buy cheap. EEVBlog (Dave) had turned me onto the Rigol DS1052 scope which I have been very happy with, so in deciding which power supply to buy, I turned to the same source. I watched a full teardown of the single supply unit and despite a fail on an early version, I was satisfied with what I saw.I have been very happy with the Korad. It's amazing what they can put together for 150 bucks. If you're a hobbyist or looking for a decent home lab supply the Korad is the way to go. If I was using this thing to make a living I'd be looking at the 800 dollar supplies, but for what I need, this supply is perfect. I like that I can see the current draw on each of the channel's displays.SRA soldering was very fast in shipping the unit. That's all I can really say about them, but what else can you ask for?The only Con:The user manual sucks! Seriously, you're better off trying to figure it out on your own than reading the manual. China needs to start outsourcing to the US or someplace that can do a better job of writing. ### ⭐⭐⭐⭐⭐ Great powersuplly for the price. *by C***Y on March 26, 2015* It's is a great high quality bench powersuplly on a budget. Fan relatively quiet regardless what some other reviews say. I wish if there would be a option so the 3rd output "DC5V" could be turned off but no it's always on.This is the "S" version, no usb so now programming possible despite some of the images on sallers ebay listing show a USB port, this is not the one ! --- ## 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.ph/products/9207782-korad-ka3005d-3s-precision-variable-adjustable-30v-5a-triple-dc](https://www.desertcart.ph/products/9207782-korad-ka3005d-3s-precision-variable-adjustable-30v-5a-triple-dc) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-18*
