Im using this for last 3 years for my 2 BLDC celling fans from 12v input to 16v output and its working beautifully. Because im living in hot climate I have added an Small dc fan to cool it down.
Excellent review. You have done a great job in testing this board. Explaining when it is getting extremely hot and when it is running cool or warm gives a good idea about this board, and it is very helpful. In your view, is this board worth buying? I have 19v 4.62a AC DC power adapter and if I connect that to this module, what will be the output current for 24v and 30v? Please advise. Can you tell me what kind of wiring you used to connect to this module? Those wires look great and well-made. Please tell me the name or if possible give me the link. I want to buy them. Thank you again for the wonderful video.
Useful, thank you. Can you also test turn-on when using each setting. It may handle a load when you slowly adjust it, but not if the load is already connected and you turn it on. Also please test for large voltage spikes when the unit is turned on (and output set to lowest V) and when you turn off (and output set to highest V). Often these units produce 10V+ spikes on the output! Specs for this unit are: Module Properties: non-isolated step-up module (BOOST) 65 * 56.5 * 23 (length * width * high) (mm) Input voltage :10-32V Output voltage: 12-35V (adjustable) Output Current: 6A (MAX) Input Current: 10A (MAX) (Please enhance heat dissipation if more than 10A) Output power: natural cooling 100W (MAX), enhance heat dissipation 150W (MAX) Easy to drive 65W 90W dual-core notebook. Use a 12V battery drive 19V 3.42A notebook, the module temperature about 45°c Conversion efficiency: 94% (measured at Input 16V, output 19V 2.5A) Output Ripple: 2% (MAX) 20M-bandwidth Operating Temperature: Industrial (-40°c to +85°c) (ambient temperature exceeds 40°c, lower power use, or to enhance heat dissipation) Full load temperature rise: 45°c No-load current: 25mA typical Voltage regulation: ± 0.5% Dynamic response speed: 5% 200uS Short circuit protection: None (Please Install fuses and protection circuits at Input port.)

Hi. I bought one of this boost converter. It has hissing sound, the pitch of whizzing sound increases as the input current increases . Is it normal or defective? I suspect it is the capacitor.
To set this to the right voltage you need a volt meter? And is there a possibility of it overcharging a laptop battery or is there a way to set it to shut off, or it shuts off automatically? Thanks

Boost converter by theory should have some load. Even small current of 10mA should help. Try that. Put a resistor that draws small current and it will project your fuse.
Do you mean a resistor permanently across the output terminals of the converter? 0.5W 1.5kohm resistor will drop 15V at 10mA (normal operating. voltage). 3.5Kohm will drop 35V (Approx max output voltage). What do you suggest?
I have a 3s lithium battery pack to charge i used a 12v 2 amp adapter set this thing clamp it to 13 volt hook a schottky diode with the bettery bms to protect this board from reverse voltage and connected everything and turned it on but strangely the output voltage fluctuates and it makes a starnge noise i tried two of this and different adpaters but same result, I am confused what's going on

I have two that stop boosting and only output the input voltage. I think the mosfet is the problem. I only use 30W of power to run a dc pump. Maybe it is not suitable for inductive load. Any suggestion on how to repair?
Hello, constant voltage means it will keep it output stable as long as your input is within the range and the power is not exceeded. I don't remember the numbers to tell you.
I believe I made this video so you know the lowest and highest voltage of this module. If I want to answer your question I have to watch it. So please watch without skipping to get the answer as I don't know what if this work or not as I have make over 200 videos of this module.
my test just gives you maximum and minim voltage and then current. See if this module can supply 150W because your speakers are total 150W and I don't remember the numbers from the tests I did on this video.

So how much your system can tolerate." anyway, is it doable to use only one trimpot to control both (identical, of course) circuits?? or connecting only one trimpot solded to both circuit causes some electrical problems?
to increase the current you need totally different values (R and C) and perhaps MOSFET and other components. so you can't change it . except adding heat sink.
Hello, if I were to hook this up to many 3.7v batteries in parallel, do you know how many amps it could draw? Is it 6? If I were to output 12v, I would expect about 1.5-2a?
I have tested and presented the result in the video. it is up to you however you want to connect it. I don't remember what was the max current for this, but watch it and whatever is the maximum current, either you can connect to one item or divide it to be connected to multiple item. For example if maximum current is 10A, then you can connect to 1 load of 10A or 5 loads of 2A.

Yes it is possible, first remove the potentiometer from the module and connect it used wires so you can adjust the output, now set it the output at voltage sensor To get maximum or high beam , now record the value for potentiometer, the n do the same and adjust it for low beam and then measure the resistance of potentiometer and that is resistor value for low beam. Now you can connect those resistors with one dual pole switch or two separate switch to turn the low or high beam value, sorry this is mobile phone and hard to see what I have typed

I presented the test. it is up you to come to conclusion. For heatsink in engineering we have a method to to calculate the dissipation of heat. But you should not go above 150W as set by the designer. the 400W boost converter module video is coming in 4 or 5 days.
I got one of these and blew the fuse as soon as I connected it to my 12V battery, no output load connected at all! Anyone knows why? Faulty board or did I do something wrong???
Hey can anyone tell me if i am drawing 24v 0.5amp from output side then how much current is drawing from my 12v battery input side ? Is it 12v 1.2amp ? And how much is total loss ? Edit : i watched full video thanks
for the power first calculate the output 14x0.5= 12W then add approximately 15% which is 1.8W losses so the input must be 12W+1.8W= 18.8W. now you can find out the current 181.8÷12=1.15A is the input current. for your second question, no you don't. Once you set it even if the input goes up and down it will stay constant at output as long as the input doesn't go below the minimum voltage. Good luck and please replay back so I know you understood it.
So if you boost volts (out)by duble of the battery capecity amps (in) also will be duble (lets not talk about power loss )approximately right ? And for second question how much tolerance (in plus volts) is enough to change out volts by plus 2-3-4 or 5 volts ?

I have the same board and it is fed by the 12v rail of a PC PSU and is boosting to 30v into a 100w led cob chip that draws 3amps but it gets red hot the heatsink and the capacitors become too hot to touch I think a fan is definitely a good idea for anything 90w or over.

Por volta dos 15A.
thanks for share.
i want load changing during 0-5 sec like 50 ohm and 5-10 sec want double, like 10 ohm. so how can i set? can you guide me thanks
are you asking to connect different load? then you will need programmable electronic load like this www.rigolna.com/products/dc-power-loads/dl3000/
you didn't reply? please always reply if someone replied to you.

i dont know whether the reply to @bilal Anwar is worthy or not but hats off to your effort . appreciated .
100w with out of box cooling 150w you need upgrade cooling
cool
Input side capacitor heats
reduce input voltage then.
@@robojax can I connect 2 in series, input is 12V battery , To get voltage of 33 volts , 6 amps . Each module set to 16V , 6 amps . What should be my output wire guage for 30 meter length at 6 amp. Will it over heat for 6 amp , 16 v out when input is 12V.
I have the same board and it is fed by the 12v rail of a PC PSU and is boosting to 30v into a 100w led cob chip that draws 3amps but it gets red hot the heatsink and the capacitors become too hot to touch I think a fan is definitely a good idea for anything 90w or over.
Yes I agree.
thanks man but that poor module was rated for 150w...
this was for 150watts , and you are using it 250-300watts
I just watch and in the conclusion at the end I mentioned that this can't handle 150W
9:04 ??? what happened
I just watched it nothing happened. I said "let's do the calculation" which was displayed a second before.
@@robojax input - output reversed
Inverter ini tidak berfungsi hanya dimonitor 12 berubah 15 dstnya tapi diberi beban ngedrop /downd
