Jesverty Adjustable DC Power Supply Review (SPS-3010)

[@davidnclearlaketx]

Very nice! Ever since my bench DC power supply died on me I've been using two of my 7500 milliamp hour drone batteries in parallel for testing 12 volt devices. I really like this power supply and it's reasonably priced also! Another great find Alex!! Every time I watch your videos I know I'm going to be spending more money! 😁💰😂🤣

[@AlexAutoFun]

LOL!! You are just like me, I don't like to spend money if I don't have to, I actually was using an old computer power supply but since I'm going to be doing some more technically videos I figured I add one of this adjustable ones to the arsenal. Cheers David!

@@AlexAutoFun Cool find! Looks good! I like it! I definitely think that you will put it to good use! 👍😁 Have a great weekend!

[@davidnclearlaketx]

@@AlexAutoFun I ended up getting the power supply after all and I think it's a good investment! Definitely lighter and smaller than I thought it would be but everything works great! Thanks again for the great review!

[@AlexAutoFun]

@@davidnclearlaketx Nice! Yeah I think that's why I like this PS, the small size and the adjustability is just what I need for my experiments. Glad to hear you like it, Cheers!

Great review. Thank you for taking the time to review this product. Amazon purchases are completely hit or miss and this helps me understand how the product actually functions before purchase. 10/10

[@AlexAutoFun]

Thanks PatRiot*, glad to hear it helped, Cheers!

[@shortliner68]

I just bought this model power supply off Amazon since there was a 25% coupon which brought the price down to almost the price of my second choice. Thank you for the review of this particular model. Can't wait to try it out on my project.

[@AlexAutoFun]

You're welcome and congrats on your new Power Supply, Cheers!

[@markstone1619]

I've been wanting a variable DC power supply for so long and just picked up this exact unit, the Jesverty SPS-3010, from Amazon and it was just delivered earlier today. It was a better priced value than the other units I saw. I set the volt and amp limits to test it out charging some small 12 volt SLA batteries and it seems to be working great. I hear absolutely no slight whine, but that doesn't surprise me as my hearing isn't great at all. The instructions saying to first set the voltage below 5 volts kinda threw me off for awhile, but I figured it out fairly soon, and was able to set the max amps, then the max voltage in order to use it properly.

[@AlexAutoFun]

Hi Mark! congrats on your new PS, yeah it's definitely workout good for me as well, specially considering it's price. Cheers!

[@TrunkThunderLithium]

​@@AlexAutoFunhow do you get it to charge below 5v I'm stuck !! Plz help!

[@AlexAutoFun]

@@TrunkThunderLithium Hi! Remember this PS can be set to either constant voltage or constant current (depending on what the application needs) You can see how I set both modes in the video. Cheers!

[@TrunkThunderLithium]

@@AlexAutoFun but that doesn't explain how do I charge my bank of lifepo4 to top balance because what setting should it be in to do under 5v??

[@AlexAutoFun]

@@TrunkThunderLithium Hi! Yes while some people use a power supply to charge batteries, I personally do not use it for that purpose since it's just a simple power supply and lacks any BMS built in (Knowledge of battery chemistry, charging requirements, rates, voltages etc would be critical for that application) This is one the reasons I only use a dedicated battery charger for my batteries as opposed to a power supply, I experienced first hand a house fire potentially caused during a battery being charged here is what happened kzbin.info/www/bejne/jpe6mH1uo9pgiKM Cheers!

[@stephenkintgen2882]

I have read the instructions and have not found an answer to my problem. I was using the power supply to test a small 12v automotive motor for a car seat. I made my connections and turned the power on. The only lite to come on was the Constant Current lite came on, no voltage reading, no current reading, no wattage reading. Since there isn’t any trouble shooting appendix in the manual. Can you please give me any information as to what I can do to cancel out the constant current light and return the power supply back to factory settings?

[@AlexAutoFun]

Hi Stephen! As shown on the video, you can switch between the constant current mode and constant voltage using the dials on the front, Cheers!

[@kenwood6802]

@@AlexAutoFunNo. The video does not show how to switch back and forth between the default Constant Current (C.C) to the Constant Voltage (C.V). Please Advise. Thank You.

[@AlexAutoFun]

@kenwood6802 Hi Ken! Switching is done with the knobs as shown in the video (feel free to use the video chapters to jump to the section you want to see). I would also recommend referring to the instruction manual as it has additional details. Cheers!

You should test the ripple voltage with an oscilloscope. If it is bad that could will be important.

[@AlexAutoFun]

Hi W! Ah good suggestion, I actually have an oscilloscope now kzbin.info/www/bejne/iGrPdGSQlNetkM0 so I will try to add this test for future reviews of power supplies. Cheers!

[@anandakaru]

Does this power suply has input voltage seletor where we can input 110v or 240v. Thanks

[@AlexAutoFun]

Hi A! Ah yes here is the 220V version amzn.to/4c0Jzwa Cheers!

[@ozzyozzy6728]

Does it have reverse polarity protection ?

[@AlexAutoFun]

Hi Ozzy! Typically reverse polarity protection is a feature built in on the receiving end (the device that needs power) not on the power supply side. This is just a standalone power supply that gives the user full control over voltage, current and polarity. So you can definitely fry something if the power supply is used incorrectly. Cheers!

[@MikesTropicalTech]

I just bought this unit and found your review. I'm having problems using it to actually put 20V into a battery system. I set the Constant Current mode to 4 amps, then connected it to the battery box, adusted to 20.0 volts and the current is basically random. I can twist the current knobs, nothing happens. Then it will jump up and overshoot to over 5 amps. If I just nudge the knob, it will slowly drop down or jump between CC and CV mode with random voltage and current values. Hmmm. I'm not impressed by this unit. It's that classic line: "You had one job."!

[@AlexAutoFun]

Hi Mike! while some people use a power supply to charge batteries, I personally do not use it for that purpose since it's just a simple power supply and lacks any BMS built-in (Or any knowledge of battery chemistry, charging requirements, rates, voltages etc. that maybe be critical for a safe charge) The other reason I only use a dedicated battery charger for my batteries as opposed to a power supply is that I actually experienced first hand a house fire potentially caused during a battery being charged incorrectly, here is what happened kzbin.info/www/bejne/jpe6mH1uo9pgiKM Cheers!

[@MikesTropicalTech]

@@AlexAutoFun Sure I understand. The unit I'm testing is an Allpowers S300 energy storage system, driving the solar power input jack to simulate charging it with solar. I haven't tested the power supply with anything else so I just thought its behaviour was strange. I'll test it with other equipment soon.

[@AlexAutoFun]

@MikesTropicalTech Hi Mike! Ah yes Allpowers, they have some good units, I actually reviewed a couple of them and their solar panels. I would be extremely careful, contact Allpowers for support, they maybe be able to help but also remember it is possible that using something else other than the solar panel it was designed for could cause issues to the unit (or warranty coverage) but Allpowers should be able to confirm this for you, Cheers!

[@barneycarparts]

BTW: its prolly obvious, but you can use the Gnd for a voltage divider say 30v from +- and insert 2 100 ohm 100 watt resistors minus to gnd and positive to gnd and get 15v at center tap gnd. Good for audio amp supplies, But I would get the 60volt 5 amp version. then you get +30,-30 or the 120VDC 2 amp version then you get +60-60 at 2 amps but its still 240 watts which if that translates through the audio amp as watts is quite a few 240 Watts. Prolly more realistically like 100 watts at the speaker. Im talking about those cheap $17 500w audio amps on Amazon. +50 and -50vdc will give you 100watts to speaker +80 and -80VDC will give you 400 speaker watts

[@KE8ODY-WV-Ares-Ham-Dad-3O4]

Would this power a ham radio and a linear amp pulling 10 amps radio pulls 10 ish too

[@AlexAutoFun]

Hi! It would depend on the voltage requirement of the radio, the 10A version will only go up to 30VDC. But I also recommend not to run power supplies at their limit, normally the rule of thumb I see is to run them at max of 75% of the capacity. So if you need constant 10A, then I would go for a higher Amp rating like this one amzn.to/46rggj0 or this one amzn.to/46mZUYX if you need to adjust the voltage. Cheers!

[@chloemcholoe3280]

Any idea what “OPN” is?

[@AlexAutoFun]

Hi Chloe! Where did you see that at?

[@johnviera3884]

OPN is available on the model with an on/off output switch. OPN is a mode so that it automatically turns on to the last selected voltage and amps output and automatically provides a power supply output. this is so if you want to use it as a dedicated power supply. Just like you would a wall wart power supply. If you set it to 12V 2 amps and turn on the OPN, every time you turn the unit on it will automatically start outputting at 12V 2 amps. With OPN off it turns on with the output in the off position

I have this PSU for the past year or so, no complains really. but the coil whine is really freaking loud, which was kinda scary at first. sure, I have sensitive ears, but to not hear this you have to be completely deaf, lol. good PSU in any case.

[@Atribuss]

More insight would be helpful, open up the case, stress load, check the components temperature, otherwise this is a sellers review.

[@AlexAutoFun]

Hi A! Ah this is my personal power station that I use for my projects related to my channel, so didn't want to do a teardown and risk breaking something or getting hurt touching something I shouldn't LOL but will keep in mind for future reviews (while the teardown idea is cool, keep in mind marking on components can't always be trusted, specially on products at this price point, the counterfeit component market is huge and detection is almost a specialized technique based on what I saw when I was in the industry).
