KA3005P - Programmable Precision Variable Adjustable 30V, 5A DC Linear Power Supply Digital Regulated Lab Grade…

Not received as mentioned. Received old version. Working ok ok

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.

I do not want to go on a rant about this power supply. 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.

This is a decent bench power supply bought to replace an elderly linear supply that had failed. I haven't tested it to the limits of its stated spec but have now used it a fair bit at lower supply currents, and I am very happy with it. A push button selects output voltage or current limit with a single control to adjust the levels. That's my only quibble: if the control is inactive for a few seconds after adjustment the control is deselected - a little longer would have, for me, been better. On the whole though it is a good PSU.

Having worked with many analogue PSUs in the past I really wanted a digital one and KORAD had two awesome models: The "KD3005P" with the jog and the 4 memories and this one. But before I decided to make this order I read about this company's PSUs*. I also watched some video-reviews on YouTube. Almost everybody had some kind of issue with all pro KORAD models, which is kind of absurd. I wanted to examine one myself and the one with the less "problems" was this model "KD3005P" with the two push and turn buttons. Also I wanted a connection with my PC so I could have a log of my work with it. This model is really awesome! No complaints by me -whatsoever- . I'm very satisfied with it in many ways.. It has a good programming inside which helps a technician (among others) a lot. This model has a three way use. First of all you can push the "Voltage button" and select each digit separately.Same with the "Current" button. Second, you can lock your adjustments so no accidental turning will increase or decrease any voltage /current setting. Attention! (The following will help a lot of users of "KD3005P" model): First testing: You will notice that you can place your desired voltage power but when trying to adjust the current the screen returns to "0000". The reason is because the PSU does not have any load so be aware that your current setting has been memorized by the unit but will not work until you put a load on it. The best way to test the unit is to connect a lamp (within 0-14V) on the leads. Another awesome feature is the USB connection to a PC. You'll get a software that can handle the unit completely. Plus it has an 'ON'/ 'OFF' feature. Simply use your keyboard to set the desired voltage /current and press "Enter". On the right of your software screen you will see two screens where you can monitor the voltage /current of your PSU. Last but not least the unit has LEDs in front that can show you when your settings are "locked", the Over Protection Current aka. OPC etc. For me it's a very helpful unit, and I'm very happy to have it on my bench. I totally recommend it! -- *PSU = Power Supply
