    Good job.
    I have another version of this module and i was confused about setting the output current, now I know how.
    Thanks.
    mine is DP60, it came with cooling fan.

    The seller must be receiving several fried modules returned. Which is why he is providing this diode solution I guess. But it feels annoying when you are buying something for accurate input/output display purpose, and then you need to de-purpose it by performing such vague adjustments. What do you think? Is it really necessary?

    Hello, good day, what happens is that on my device, it does not output voltage, it only shows 0.06, 0.05, could it be a specific damaged integration that I should change? Could you guide me a little, thank you

    this module can go upto 12amp at 12v.....You didn't turn the potentiometer while the constant current light was glowing. You should have to do that to get the maximum current.

    Does buck converter can use on lights or LED lamp light bulbs?

    • @WattHour
      @WattHour  ปีที่แล้ว +1

      yes. it is just a power supply. The buck means the way the voltage is reduced.

  • @irfantat4172

    At 24:44 the efficiency is was calculated incorrectly. It's supposed to be around 97%.

    • @WattHour
      @WattHour  3 ปีที่แล้ว

      Thank you for pointing that out. I might have made mistake, but quick view showed it is correct (output power)÷(input power)=(29.8x5.2)÷(32x6)=80.7%.

    • @irfantat4172
      @irfantat4172 3 ปีที่แล้ว

      Look again; i don't see a 6 amp, sorry. I see 4.99 Amp at input. So (29.8x5.2) ÷ (32x4.99) = 97%

    • @WattHour
      @WattHour  3 ปีที่แล้ว +2

      You are right. I can't fix it now. I noticed that the drop of efficiency but ignored it as I was thinking this is how the module is. I can't remove the video. Thanks for pointing it out. I will put a not in the resources page for this video.

    Do you have any idea about why that happening

    • @WattHour
      @WattHour  7 หลายเดือนก่อน +1

      Hi, is the output at the voltage when there is load or without load? may be the potentiometer is bad. Not sure.

  • @blggtavus
    @blggtavus 3 ปีที่แล้ว

    Is it safe for the module to get an input from solar panel to charge a battery? As the input current and voltage is not constant.

    • @WattHour
      @WattHour  3 ปีที่แล้ว +2

      Yes it is as long the voltage is within the range.

    I have this module also but my problem is how to adjust to the maximum output current for 14.6v output voltage...my power source is 19v 12.3amp..what do you think is the max current output of this?...

    • @WattHour
      @WattHour  3 ปีที่แล้ว +1

      Calculate output power and subtract about 14% from it , this is the input power. I made this video to answer such questions. Please watch and you will have no questions left.

    I just got that module. i have one question. When i allready charging a 12V battery through the diode - can i bypas that diode to get rid of Vf loss at that diode? As i understand, that diode is for protecting the board when Vout is 0V and output gets connected to battery. When Vout of the board is higher than Vbat - can i shunt that diode?

      May be you missed when I said : buck converter. This is reducing the input voltage. Look for boost converters. I have so many of them.
