600W 0-66V 0-10 A curr and Volt adjustable charger for 120$

[Doctorbass]

I found these great PSu on ebay that ALREADY have the current limit adjustable and voltage too.

not bad..

even for 30s lipo, two of these in serie for 240$ SHIPPED is a good 1200W charging solution

Doc,

In your title you say 0-66V. How would you run this 60V power supply at say 38V, when I see it says +-10% Voltage?

I am thinking to initially to use one to power a 3010b icharger, and then maybe later on bulk charge in series.

Thanks, Richard

Putting 2 in series will still be charging at 600W [each]<=edit but double voltage, right?

So, total input from electric outlet socket/plug is 1200W. Total weight for 2 units is about 6.5-lbs.

Good find Doc. You always find great stuff for batteries...

Someone should ask for the spec sheet to see how efficient these are at 110-120v.

They sell other voltages too. In your case a 36v one would work and put out about 16 amps.

When you connect your empty battery on the psu, the voltage drop below the adj range but it will work anyway

Double the voltage and keep current the same and you double the wattage too.

But, you snipped or left-out my next sentence:

So, total input from electric outlet socket/plug is 1200W

In other words, each charger in series is still only consuming or charging 600W each x 2 units.

[amberwolf]

Well, I wouldn't really recommend stating it the first way:

Putting 2 in series will still be charging at 600W but double voltage, right?

because while strictly true it is not the best description if you're trying to discuss total power (Since AFAICT Doctorbass's statement you were replying to was talking aobut total power).

Instead, you are charging at 1200W, at whatevef voltage and current the total of each is (so twice the voltage of one, but the same current as either). It all means the same thing, but one is clearer (to me, anyway).

Yeah I posted these a while ago, no one has tried them but I'm considering buying one soon to put in series with my xbox power supplies. I will report back if I do!

4 transistors vs the usual meanwell clone 2 - I'd love to see how they plan to share the current here (probably low value resistors) - or something exotic like dual in-phase windings. At least it has a half-way decent heat spreader on the transistors.

I might get one of these just to reverse engineer the design out of interest.

Looks to be about the same physical size as the 350W meanwells, I would not recommend running these at their rated current without upgrading the cooling! More watts per cm2 = more heat per cm2. The fans from a HP DL380 G3 etc are ideal for this - but would need to be mounted on the outside (and the power supply would need to be thought about - they draw 1A each - and yes, they are noisy!

Weight on them is pretty good too, 1.5Kg is respectable for more than 500W

[dnmun]

i see them saying '4 diodes' so maybe they mean the rectifier bridge.

i doubt if they mean there are 4 push/pull NPN transistors for switching the front end.

i can't see them splitting the load for the transformer that way.

if someone does buy one it would be useful to see the insides.
