best ac dc converter

I have purchased 4 of these cheap converters from aliexpress. I purchased a hong poe 110v ac dc converter on 3/9/2024 as a replacement : https://www.aliexpress.us/item/3256...t_main.52.21ef1802wN8ucC&gatewayAdapt=glo2usa

This is the first one that felt so heavy. Like twice as much as any of the others though they are similar in size.

I'm wondering if anybody knows or has seen a deal on an AC to DC converter from one of these manufacturers that is in a Range close to the one I just listed. By anywhere between 60v and 150v. The ones I'm finding are over $200 and I'm struggling to find one that can output at least 60 volts.

I would also like to know if anybody is purchased a Chinese converter that they've had good luck restaurant a reasonable. Of time. Even if it's not in the proper range because the manufacturer likely provide other voltages as well.

This is just a interesting conversation going on in my head. It'll probably be sometime before I upgrade to something like that. I'm just digging for leads to find appropriate units.

You could yoink one out of a treadmill. They only do around 5A though, and output voltage is typically not infinitely variable, rather in fixed steps corresponding to the number of speeds on the machine.

Not precise enough for battery charging, if that’s your intended application.

In general RV products IOTA makes a very good AC to 12VDC converter/charger55 amps. The owner of Boat and Rv Accessories told me this brand had the least returns ( for fixing or failure).

To get higher DC than 12v you run the 12v thru an (adjustable) boost converter. Search boost converters on eBay and you will have plenty of low$$ choices. Most of my purchases of have worked to rated generation.

If you want less than 12VDC , the item to do the change is called a buck converter.

What specifically do you need it to do? Meaning, what is it's intended use?

There are different ways that various converters work, so that they are suitable for certain uses but not for others. Most, for instance, won't work as battery chargers because they just turn off when the load exceeds some amount--for that purpose you have to get a CC/CV type output unit.

FWIW, a heavier PSU usually means it's built better, if it is otherwise "rated" the same and designed the same, same size, etc. It's not uncommon for lighter units to leave out parts to save money, or use caps, transformers, transistors, and even heatsinks that are smaller than they should be for the "ratings" the unit is marked with (vs what it could actually sustain).

Actual Meanwell brand (not clones) PSUs are generally well-designed and well-built but usually cost more than the cheap clones. They make a bunch of different models / series for different purposes with different features, including ones that are totally sealed against weather/vibration/etc (I use one of the HLG-600H-54A's built onto the SB Cruiser trike as a charger).
