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

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

Doc

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... :twisted:

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

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: :lol:

In other words, each charger in series is still only consuming or charging 600W each x 2 units.
 
Well, I wouldn't really recommend stating it the first way:

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!
 
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.
 
Here some pics that are on the "500W 48V 10.4A Switching Power Supply With Current Control" sales page.

There are lot of versions of these available , different power ratings, voltages, etc.
Some do have fully adjustable voltages ( i have 0-30v version) and current limiting, but i have not seen any with actual "adjustable" or "Constant current " features. They just run at whatever the load resistance and set voltage allows,.. up to its max limit.
In that respect they can act as a "quasi" bulk charger if you set the voltage to the pack maximum, the charge current will tail off as the pack reaches max charge voltage, and even eventually drop to near zero.
My 400W version cost $30 delivered.
