How do you adjust the output voltage of this converter to a desired voltage, say 4V for example

Adjusting the little gold screw on top of the small blue box (variable resistor) next to the blue terminal connector.

There is a small blue potentiometer on the end by the input power terminals. Also I've seen this put out up to 38v when using a 40v power supply

A brass screw on top of the Blue post sticking up adjusts the voltage, Need a meter to get the right output....very easy.

You can adjust it with the potentiometer on the board, but you are going to need a small flat head screw driver and a volt meter to do it, there is no voltage read out on the board itself.

No adjustment available on this unit. You might consider installing a current limiting resistor on the output. Great unit with such a wide range of input I use it with a solar panel and packs of spent alkaline batteries for phone charging.

This converter is a 12volt input with a 5 volt output , I don't think this is what you are looking for,however they might have other step down converters to choose from,I hope this helps you out.

It seems to me that the International Voltage Converter in the picture goes from 220V to 110V and therefore it is not what you want ( from 110 to 220)

The output voltage is constant from power up. Constant at the voltage you set it at.

Make sure the power supply you are trying to use is the proper voltage and DC output.

It is not a voltage converter. just a power strip, will pass whatever the source voltage it gets. So you should get an additional converter.

The only adjustable thing I can find on it is that you can apply either of two voltages to it either 12 or 24 volts dc to it with the consequence of a same output 5 vdc out of it. That is the only adjustable part I can see on it.

I cannot answer this question directly but, here is a web address of a company that sells converters for this purpose; http://www.walkabouttravelgear.com . After reading the information on this site I noticed it addresses the conversion of the voltage but does not do the same for the hertz. However, a call to its 800 number would most likely resolve this.

I am sorry you are frustrated with the converter. My advice was only to let people know what is technically available.

The potentiometer adjusts the output voltage. Power it up, put a digital multimeter on the output terminals and adjust the voltage to what you want or need. I would also suggest that you re-check the voltage under load to make sure no values changed.

No, the device only works as a buck converter, so the output will never be higher than the input. If you want to have a higher output voltage than the input voltage, you need to look for a "boost" converter. They are not as common as the buck converters, but there are many of them out there, all you have to do is search using the words "boost converter". You will then be able to put in 5 volts dc and have 9 vdc on the output.

I use a voltage adaptor with mine. It is a great product. It can take a couple of batches to figure it out once you do you will be making your own all the time.

The instructions that came with it explained how to change the voltage, Unfortunately I have lost mine

Yes, you can. Remember that this is not a converter, it is just an adapter. You should be sure whatever you are plugging in can handle the the higher voltage and do its own conversion.

To do what you're asking will require a Converter from Black Magic Design. Hope this helps!

I used a converter box I got from RedioShack to covert 110 volt plugin to 12 volt
