Using a boost converter, a long piece of thin wire and a switched mode power supply to carry DC current over a long distance.

Good morning all…

ran a shack out in the bush on 2km of speaker wire by kicking mains up with a MOT, and back down again at the other end.
illegal as all hell, but was fine… could pull about 4A at 240 before the sag got too bad.
enough for some lights, radio, telly.
did simular…
40 v solar to round 2kv ac (microwave Transformers) and then back to 40v dc .
over a length of round 500m.
i did this as landline (on 3 m posts…no voltage against ground.
) i use cattle wire and insulators it is working fine since 12years;)
sorry for my poor english +!
Good evening dude . Nice video
You could use an DC – AC inverter
I know this is older video. Do you remember if your fan is on all the time or it kicks in when heat increases. I am charging at 1A 42V and fan doesn’t kick in. Is that normal?
It say rated power 17watts, so 12v 1amp + 5v 1amp = 12watts + 5watts is 17watts .
Has anyone managed to get over 5A @ 110-120V on that b900w converter? I am getting anything between 200 and 500W on that module, depending on the in/out difference, voltage, current and so on, but nothing close to 900W, no matter what I do…
For someone that's quiet clever with electronics you seem to have made the same there are a lot of people do when they're looking at the specs of these boards, probably due to the way it was listed on eBay being incorrect too, but still.
Virtually all of these power supply, Step Up modules, buck converters the max rated current supplied I'd in relation to the "imput", but many get it wrong thinking that it is relation to the output.
This one is rated at 1a and that at 240v AC is obviously 240w, and if you subtract some 10-15% efficiency losses you could assume 12v 17a /5v 40a.
hey . . . is it possible to upgrade this to output 150vdc on the 900w version?
Bad IDea, just for the conversion deconversion you lost 30% of the available energy, thick copper will be a better solution on energy point of view, and also on the price point of view
Hi, is there a video here that features only the MingHe 900 watt Boost Converter please?
The blue 'blob' on the AC input is a varistor, (VR marked on the board). Its resistance changes with temperature and drops to a lower value when warm, allowing more current to flow after a few seconds of operation. Its task is to reduce the inrush current when cold at startup.
