Episode 550 XYS3580 DC DC Buck Boost Converter CC CV 0.6-36V 5A Power Module Adjustable Regulated Laboratory Power Supply Variable from Banggood Be a Patron: / imsaiguy
at 6:12 what does it have to do with low input voltage?? the device is gone into CC mode because you set the current limit at 0.3A and connected a 50 ohm to 36V. of course voltage will drop to keep the current at 0.3A. that's how any current limiting power supply works
I have this regulator since a month and it works just perfectly. Ever heard about initialization ? The delay you talk about between different setups is only initialization which is a normal process. And of course you cannot change the voltage or current once outside of the menu. This is clearly for protecting the load or circuit connected with the regulator.
please make another video of this module about load test for long time and how fast the temperature increases, about memory location and quick access of that
It's made for for supercell capacitors it works as a voltage feller to keep up with the need off power in a group of 15 or 90 capacitors if you will put a group of capacitors on the output side you will see a super change of power in milliseconds you see the voltage stabilize and the amperage escalate dramatically its a door to a new power suply
Good review! Can you tell me how well the over-current protection works? I have a simular (Chinese) buckconverter module, and it does not do a good job of the over-current protection. It actually first goes up to the set voltage, and after about 200ms it starts checking the maximum current that is flowing. If it's too high, it then starts to lower the voltage. This means that for at least 200ms you could get a massive over-voltage (and of course allso over-current) before it kicks in the over-current protection, effectively destroying your component due too the late protection. Is this module doing a better job?
As a radio amateur, one of the things I worry about is RF noise, particularly with switching mode power supplies. Would you consider this power supply appropriate for a QRP rig? Thanks DE WA1KLI
As a former SMPS project engineer and a fellow Ham too, I would say it would make a very good noise generator within the same room as your radio or near your antenna. Possibly anywhere in your house too ;-) Even 110v LED bulbs can be really nasty if you are on the HF bands...
@@IMSAIGuy I will be using it in the ham room to power the 20v laptop from the main station battery (12.5 volts ) so i will find out pretty soon , but looks okay so far , you can also put it in a metal box and use from AC line noise filters to tame any rfi.
I think something is wrong with the board, since I can't limit the amperage that is being applied to the circuit, and most of the times it won't display the current amperage and power drawn from the power supply (stays at 0A and 0W). How can I tell if something is damaged and how could I fix it?
Same here too. I've tested many ways but ampere doesn’t meet the output and few second after it shows a warning like " OEP" and restart. I'm confused what is it and why is it happened l??!!
Hello, everyone. The input power is 12V, Low Voltage (LVP) appears on the LCD window, and after 10 seconds, LOCK appears. Please tell me how to release it
you can get them on ebay for about the same $. yeah you can write neg reviews on BG but be aware that mfr's selling on BG or Aliexpress don't make the most robust electronics. it's the cheapest outlet for a China product
Maybe autoscaling would be better if it kept a lifetime history. This would need a reset somewhere but at least you would have some idea of what the graphs ment at a glance.
The most annoying thing here is that you have done so many tests. But, forget to change the current from .300a to 5amps. It defeats the purpose of testing. Beleive me, this device can easily do 5amps at 12 volts is you provide it the right power. Rest things you can figure yourself.
Plus he keeps complaining about the lag, which is purely the output capacitor charging/discharging as will happen with any power supply. Plus he also keeps referring to his 50ohm load resistor which i can guarantee is not exactly 50 ohms at best this resistor will be a 5% tolerance one, plus as it warms up the resistance will change. He as others have stated keeps referring to CC as being current compliance which is wrong. CC stands for constant current. He may have a good technical background but his practical knowledge is obviously very limited .
Can you share your electronic load scematic w me. Ive been thinking about designing one myself but I would love to see your solution. BTW what is your call? DE K9IC
you can see the schematic in czcams.com/video/OlqymCSZ4Ek/video.html I don't give my call since it would give my identity. It is an extra call, I'm WAS WAC DXCC 73
@@IMSAIGuy thanks, vastly similar to what my concept thinking. I was planning on a much higher version with a few FETs. I would like to get up to 100A. I understand about you maintaining anonymity. When you're famous you need to have a low profile. I am infamous so I can throw caution to the wind! 73 and stay safe
I think you need to do some research on power supplies abs CV and CC. You have it set to CC of 300ma with a 50ohm load at 36v. What do you expect it to do. It’s current limiting You really don’t know what you are doing
Hello. The XYS3580 module (LCD display) has a very poor performance. On 50W load test, the XYS3580 heats up to + 70 ° C, while the XYH3606 module has a stable temperature of 33 ° C. The XYH3606 module does not have an output anti-reverse diode, one must be installed if you want to recharge a battery. I made a power supply with output out 0V to 36V 120W compact autonomous rechargeable from 15V to 24V IN (power supply off or on, it doesn't matter) in an aluminum box of 130Lx110Wx50H mm, 6 18650 batteries mounted in 3S2P, bms, regulator battery charge limited in current (1.4A), USB module 2.4A QC2.0 / 3.0, etc ... 30mm regulated case fan, etc ... This power supply operates on mains and / or internal batteries which are recharged as soon as the IN sector (15V to 24V) is present. Regards
but cost is too high :( for your specified model.. specify what is meant by poor performance in 3580. only heating is more or any other draw backs. thanks in advance
I have a similar, and what you expected is what I did and it was a let down. I paid £8 for mine free postage. But I think you ended hitting the nail on the head. If you set then power it's fine. Active adjustment isn't good. I had issues trying to set voltage as it set amp and would volt to what it likes you have to use the settings (long hold power) to set limits (not min) With power the amps can't be finite.. This is what annoys me, it was sold as a solar charge controller. Which I guess as that, it would work. It says DC to DC boost buck also. But set and forget... For an hour due to the auto off function!...

BEWARE: XYS3580 is not fitted with OLED display as this review claims. The operator makes a number of other mistaken statements.
Is it possible to manualy change output Amps?
Do you think it can be powered with an ATX PC power supply with 12V output (offers 15 Amps)?
Is there a specific way to turn it off ? or just unplug the supply ?

yea trips off line it over current...
Nice review. I was wondering if you had a chance to measure noise / ripple on your scope?
looks really good so far, going to use it for the laptop in the ham radio room so it will have to be clean from RFI
I have also this type but with WiFi but I dit not get it to work on wifi
is good for voltage injection?
As a radio amateur, one of the things I worry about is RF noise, particularly with switching mode power supplies. Would you consider this power supply appropriate for a QRP rig? Thanks DE WA1KLI
I haven't looked at any noise it gives off. I know what you mean, I have to turn off the lights in my garage when I use my HF rig.

soulds like you might be using it wrong. the menus and operation are confusion. Did you press the yellow button to enable the output?

Are the outputs totally isolated from inputs or is there a common?
common

could you use this to charge 8s lifepo4 battery? it needs 29.2v to charge .i was thinking about using this to make usb c pd powered e bike
Lipo batteries need to be charged with a special charger not just voltage and current.
@@IMSAIGuy yes but i am asking if it charges lifepo4 batteries. Lipo and lifepo4 are completely different things :)
For lifepo4 you only need battery + and battery - contacts to charge :)
@@nebulous962 ok, have fun. the device is rated to 36V
okay ty :) have a nice day :)
I never buy from Banggood any more. They don't print negative reviews! (or at least they didn't in the past...I haven't checked lately)
you can get them on ebay for about the same $. yeah you can write neg reviews on BG but be aware that mfr's selling on BG or Aliexpress don't make the most robust electronics. it's the cheapest outlet for a China product
these are pretty cute, but not for precision troubleshooting I think
absolutely not...
Maybe autoscaling would be better if it kept a lifetime history. This would need a reset somewhere but at least you would have some idea of what the graphs ment at a glance.
"Compliance" is a term generally used to spec the voltage range of a current source (or similar concept). I wouldn't use it as freely as you are...
I have this unit since like 5 months ago and i love it, but its an LCD, not oled
Link?

DUDE - I want to know if it will power a laptop, 20V, 90W power supply. Not a bunch of nano-farts.
no
It will, probably not sustained at 90w though.
