      I love these supplies. I used them to build a variable DC supply for my bench. I changed the pots for panel mount 10 turn pots and fed these supplies(3) with a high current 24V supply. Most of the parts for this project were source from banggood including the laser to engrave the front panels.

      Incrivelmente pequeno, mas muito bom! A encomenda chegou sem atrasos e sem problemas, nada danificado e bem embalado. Já testei e fiquei muito contente, coloquei na entrada 22 Volts DC retirados da minha fonte e foi regulando a saída e tirei várias voltagens como podem ver nas fotos. Por isso recomendo, não aqueceu e por fim digo que é um bom regulador de DC para DC. Temos que ter atenção em não ultrapassar a voltagem máxima permitida pelo fabricante.

      Obrigado Banggood

        Q: Can use this device for300w 30v solar panel 12 or24V battery charging purpose?
        A:
        I think no, because this coverter is not designed to made the solar panel to work in its maximum power point (MPP). Solar panel hasn't an its own voltage, it depends on the point you made it working, with the load you connect to it. Solar panel can work without problems from open circuit (current is zero) to short circuit (where current is maximum but voltage is zero): in both cases power output is zero because is the product of voltage and current. Between these two extremes there's a desired point where power output is the maximum, changing continously with solar radiation and temperature, so needing an electronic able to do a tracking. In simpler battery plants, generally is battery that imposes the voltage, and the solar panel model is chosen accordingly to this voltage to have a MPP close to this voltage: it's not a tracker, but it works.

        Q: I want to bring the LED diode on the outside. What kind of diode can I use, what features? (the diode has three terminals). Thank you.
        A:
        If the LED diode has three ends must be of several colors you must identify the negative and the other two terminals are positive. you must also place a resistance taking into account the maximum working voltage; I suggest you study the law of ohm (do not place it without resistance because you will damage it)

        Q: how much ohms has the potentiameter to make a diy bench power supply
        A:
        Trimmers on PCB are 10 kOhms. Replacing them for a beanch power supply, I recommend splitting the voltage one into two potentiometers in series: one 10 kOhm for coarse and one 1 kOhm for fine regulation.

        Q: Can multiple modules be put in parallel? I have a DC input of 180V and would like an adjustable output (20V to 120V)
        A:
        I think not. You can't be sure that the 180 Volts equally divide themselves among the modules' inputs (in series), furthermore modules' insulation is low.It is a simple circuit made for standalone operation, and in general commonly used DC-DC converters have input voltages limited to less than 100 Vdc.

        Q: Hi, I want to step down from a 20 volt Li-ion battery, to 12 volt and shut of when voltage of battery reaches 16 volt. This to protect the battery. I want to use my old 12 voltage tools with a adapter and your product. Can it do that? Yours sincerely Jan
        A:
        No, in your case with the voltage drop on the battery it will be problematic to get a stable 12V, for example in my case this product is used in conjunction with a 19.5 Volt power supply from the Dell laptop and receive on output 12V to operate my devices.
