Near 20:51 I said if I "brought the voltage down it would get us closer to 300w" which is obviously incorrect. I was looking to increase the amperage by turning down the voltage. Without changing the load, the overall wattage would not have changed. These are issues that get removed in production videos that can't be edited in live videos. Sorry for any confusion I might have caused.

I appreciate that your an RC guy, using tour supply to charge batteries, anf I'm sure this unit serves you wll in that rile. But here's a note for the electronics people out there. I just bought this, and tested it. At 10V and 1amp it's ripple is 400mV! That means it's output voltage is fluctuating nearly half a volt at high frequency, and that makes this supply entirely useless for electroncs work.

I've had really good luck with the Korad PS's I bought. 0-30VDC at up to 5 amps. I use one for plating, and the other for electronics projects.

Really good video. You showed a really good solution for charging a couple batteries at 1 time. I have been charging in par for years. It works fine.

I found a similar from Amazon Sweden after your video and I have already used it for some charging of small batteries and connected to a receiver in a plane to get things set up, very good addition to my bench, thank you for the tip! I don't really trust myself to not mix up red and black, so I have a long lead going to a XT60 and then I make the different connectors that I need with short cables and a XT60 at the end, saves a lot of cable and I only need to make sure that the connection is correct when I solder. Making sure I have no more than 5V into my receivers, that is a totally different thing...

It does look pretty decent. I use two repurposed £12 Dell server PSUs, rated at 60A at 12V. I use one for my outside charging station. The other, on my bench, feeds my ToolkitRC M7 charger/power supply. If I didn’t have this setup, I would strongly consider the item you reviewed as it’s neater and quieter than my kit!

Will this be suitable for breaking in slot ca motors? I need something that will show the increase in amps as the brushes break into the armature. I assume in you have the power supply set to CV the amp meter will show the increase in amps throughout the break in process. Thank you.

Hey, what about the Ripple? Can you measure it with an osciloscope? Thanks!

[joeishere]

I’m planning to use one for vintage phone testing, most of their batteries use 3.7V. Knowing you can change v number by one digit should I use 4V?

I also bought this exact same unit and have found it to be better than average for build quality, performs to spec and overall value for money. It's not as good as units from high end brands but it would be wrong think that it would be at a tenth or more of the price. Couple of things to note, dull solder joints in modern equipment is normal, reason, lead free solder tends to be dull. It can be shiny, it just depends on the flow solder process settings. I have load tested my unit and it does meet spec. In fact, I've load tested it for about 12 hours at full output and it came out of that with no sign of distress. This was on a Kikusui electronic load. Component wise, the highest quality components will never be found in units at this price level, but for non commercial use the average hobbyist should get an acceptable life from this one, especially if it doesn't see continuous use at high power levels. So I would happily recommend this unit, at the price it's difficult to beat.

Govt auctions unload beefy power supplies sometimes. Also they are currently dumping commercial DJI drones due to the recent ban

10 amper 30v waat göstergeli sivic mod hafiftir bence çok iyi

[kenjackson]

Thanks for the great video. I am the most basic novice there is to electronics. I am looking to buy a bench top power supply for the average electronics projects out there. I’m asking because if I also, want to test automotive gauges and such, this looks to be the cats….”bum”??

Ripple is best on a scope, but just set your meter to AC volts and read no load and loaded.

[VinhLe-yrgw]

I thought this is in the "electronics " realm, not "electrical" like wiring house lighting, installing AC power sockets etc :)

[michaelhawthorne]

Anybody who derides a Fluke is not worth listening to.
By the way, your PSU is SMPS (Switch Mode Power Supply) and not a Linear.
SMPS is great for the weight of the PSU and can produce insane current values.
If you are powering sensitive equipment or Audio related circuits....then a Linear will be needed.
These will be bigger and weigh a lot

The device looks good and seems to be of a decent quality. I'm using something similar. Although, for very low voltages, I prefer to use one of those "DPS" power supplies from RuiDeng.

My only real point of criticism would be the USB port at 4.3 V at only 0.7 A load is really bad, to be honest. iPads can draw over 2 A from a USB charger and I don't even want to know how low the voltage would drop then. Just compare with the Apple charger, which should stay at 5.1 V even at 2 A current draw. I'm using a simple multi-port USB power brick on my bench, they don't take a lot of space when powered with a separate mains power lead and can stay powered permanently.

Also these bench power supplies are usually not made for permanent operation. It may not be very efficient as power supply for chargers. To power chargers, cheap and used server power supplies are ideal. I'm using a 1kW HP for 12 V and two in series for 24 V. Of course, I'm not nearly using that much power, but at the power I'm usually drawing, the fans won't even turn on. And I still have my bench power supply read for use.

Main problem with these cheap PSU's is the noise, back in the day, even though switching technology existed, brand names still stuck with Linear designs to lower noise at the expense of larger sizes and more expense on bulky transformers, if you want a good power supply for your lab, and do any kind of microelectronics, you are better off getting an old power supply from the likes of Hameg, Fluke/Philips, or even an old RS/Farnell supply, just remember to replace the old electrolytic capacitors as they will have dried up.
Those looking at the insides, PCB's these day are usually soldered well, things to look out for is cable management, cut-outs near high voltage sections for arc-over, good smoothing caps and the ilk.

Yeah, I bought this one. I'm trying to charge a 210 ah Prismatic cell, and it starts off at like 7 amps. The stay is high for about 5 or 10 minutes and start going down. Then it goes down to 2.2 amps. At slowly keeps going down. Did I get a defective machine or something wrong with the battery?

[p__jay]

i've bought that power suply...now if i set it to constant voltage @ 12V and connect a motor, it switches by itself to C.C. and draws whatever it wants....WHY? is it broken or the way it is? if so its completly useless...
