Wow! Very useful video i am looking for some manual adjustments in volts & amps, and here we got a solution. I dropped a sub I think Buck converter can perform well in the long term use if we don't exceed the limits above 40V
kya hum ise 19 volt 8 amp power supply lagake 14.7 volts , 7 amp pe set kar sakte hai? 12 volt 80Ah Car battery charge karne ke lye! without fan. aur kitne der tak continue itne power pe chala sakte hai? Please reply. Thank You.
Current always depends on the attached load so in a real world scenario, a constant current is usually a current limit supply. To keep the current constant, you can limit it but If the attached load imresistance is increase ethen to achieve the same current, power supply will need to increase the voltage which is not acceptable in most situations. Therefore when we refer to a constant current power supply, it is almost always a current limit power supply just like this one.
@@researchcell but that's not accurate because a constant current supply does area the voltage in order to keep the current constant and there are plenty of those in the world. I think you should be more accurate by using the word current limiting instead of constant current
@@researchcell a true constant current supply operates as you indicated and it is a much different function then current limiting hey.. the two terms should not be used interchangeably
As per my experience, The maximum output current you can safely get from xl4016 is 8A or below and since it is a stepdown module, the input current will always be lower that the output current so i would say that operating this module at 9A or more can damage the xl4016 IC. It is wise to stay below 8A.
I've bought one of this but mine wont change the voltage output. If I connect 12V, on the output is also 12V no matter which way I screw trimmers. Same with 3V and 5V. Any suggestion where could be the problem?
@@researchcell I tried. Same result. I "fixed it" with a 10 ohm 10 W resistor as a load. Before that I connected a DC motor as a load but I guess its resistance was too small. P S. I also give it a couple of turns counterclockwise. But before I connected the DC motor I did a couple of turns in both directions and checked with the multimeter but in and out voltage was the same as I described in previous post.

Yes you can. You can also adjust charging current.
This is not a true constant current power supply but a current limit supply, is that correct

Can input this between 9-10 Amp

What is its noice level? Can i use it with amplifier?
If You use a large filter capacitor then I think yes.
Thanks for giving a comprehensive review. There is a open space for and LED, do you have idea what is it's use?

May be the trimmers are faulty, did you try to turn them all the way on both sides?

You are right, buck and boost converters act weird without loads.
