Thanks for sharing this video and information. I just ordered one from Amazon today and estimated delivery is only 2 days 🤩😎. I am building an electronics workshop for Amateur Radio and model railroading projects. Also including Raspberry Pi & Arduino Uno / breadboarding and software development projects. Appreciate your help in this area. Just discovered your CZcams channel today this was the first video I watched.
Yes dr meter now
Hello. 3 years have passed. how did this power supply perform? could you recommend it? Thank you.
Can you hook this up to a 1000 watt car amp with a car battery on a bench test.
The photo shows that there is a positive and a negative trend. How can I get the negative voltage since the negative pole is connected to the earth. if I disconnect the short circuit I will get a negative indication; I didn't see anyone attempting it. WHY?
Any good for a shortwave receiver? Excessive RF "hash"?
Stumped! I'm trying to top balance some new LiFePO4 cells using its
constant voltage mode. Directions tell me to turn the amp knobs
clockwise all the way, then set it to my desired voltage (3.65v in my
case), then connect the battery to the terminals. As soon as i do that,
it reverts to the constant current mode. Any idea how to keep this in
constant current mode?? Any help would be much appreciated. thanks for
the video!
Hello. Unfortunately I have never used this power supply as a battery charger and I cannot help you!
Hi, Does this have an alarm system to detect short? or even able to handle it?
And do you have an opinion about wantptek dps3010U ?,
I need an input. After seeing both, I think Wanptek is interesting to me. But I did not find reliable reviews about this brand. Can you help me? in your opinion, which would you recommend ?.
Looks same as Kaiweets? What are your thoughts?
It looks the same. It will certainly be rebranded but with the same electronics.
Exselente fuente compre la mia y todo muy bien
What is the price of PS 3010DF ? And what is the price of NPS3010W ? Please tell me I need.
PS 3010DF US $ 93.61 - NPS3010W US $ 76.99
it's dr meter!
Hello. I want to buy a power supply. Help me choose. I liked this one, but there are more options. What say about these? KPS3010DF, NPS3010W.
Hi, there. They are very similar. At this point choose based on price and aesthetics. I personally like this: www.banggood.com/custlink/Km33iVYt7l
@@cosmochannelvideo I think 4-digit accuracy is important. How do you think? Is the power the W display needed at all?
@@mihails1814 Reading the values on 4 digits is of course more accurate than having only 3 but of course it depends on what you have to do with it. A 3.5v powered LED if you feed it at 3.51V or 3.59V doesn't change anything. If you need to have really stable and precise power supplies then you have to change the type of power supply and add a lot of dollars. Being able to read the watts is certainly convenient but I never served and then just multiply VxA to have the watts.
@@cosmochannelvideo Thank you.
@@cosmochannelvideo And as regulators here what is used? Potentiometers or multi-turn resistors?
