KORAD KA3005D - Precision Variable Adjustable 30V, 5A DC Linear Power Supply Digital Regulated Lab Grade…

Got what I needed

This device is just perfect if you are an older guy who went through his fair share of wrestling with those old trafo-based, fidgety, no finley-adjusted PSU's, energized outputs, available at the market 10 or 20 years ago. Pros: - stable output even under max loads - no overshooting or any weird spikes - capable of adjustments on non-energized output - digital interface capable of fine adjustments - clear to read and functional with memory options Cons: - ... If you are in need of a good bench PSU just buy it. I already have two of them, seriously considering buying a third one...

Very happy with this power supply. Love the ability to limit the supply current down to single milli Amperes, very handy if you are working with Leds and need to take the current down to 14mA. Also like the ability to have 4 preset outputs as well. Just get yourself some extra banana plugs with leads, as there werent any supplied with the psu that I received

Mas de un año despues, todavía la tengo y sigue completamente funcional, tal vez lo unico que haga es ponerle un ventilador mas grande, pero por la calidad de la fuente, estoy completamente satisfecho

I reduced one start, because the provided image did not match the one i received. yes it has the same model number, but the display panel does not have watts digits like in the image, when i googled the same image i did not see it in the Korad official website, however some people in youtube have it with slight change in model name by adding "s" letter e.g. KA3005DS. Also the box did not include test leads as stated in item description, luckily i have lots from my previous devices. overall the item i received still great regardless of the missing parts with different display panel. It just serves the purpose...thanks

Bought it a year ago and it's been working great with no complaints or concerns. Turns on every time and does what I need it to. Controls are quick and convenient and the output toggle is awesome so you're not removing/replacing leads every time you need to adjust the power supply. These seem to be the most noticeable things you lose out on when you buy a cheaper bench supply, but aren't a concern here. When I was researching the purchase I was concerned by how many people seemed to be complaining about fan noise... I used it for a weeks-long stint as a power supply for a ham radio and the fan is probably the most inoffensive noise I can imagine. The only part of calling it "a little loud" that's accurate is the "little" part. For the hobbyist or prosumer, I think this is exactly the right price point to balance quality/features and cost. Don't go any cheaper. If you're feeling rich, grab a used HP/Keysight unit for about twice the price.

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.

Llegó antes de lo esperado, funciona perfectamente,
