How hard can you push a meanwell?

Guys.. I think thet question of this thread should not just cover the low power meanwell.. :wink:

The 1000 and 1500W model are also really interesting!!

and since this serie is made of higher quality ( RSP, RCP, etc) they have many good feature for power, current and voltage stabilisation.

Generally they indicate overcurrent rated 125% max

that mean they sustain 125% of their rated current no prob!

In fact, my 1000W meanwell ( 48V 21A) really charge at 1250W continuous DC output

and the 1500W is 1700W Dc out from a single 15A 120Vac outley...

Sometime i dont understand why many are using these 500W model and that theiy add 100$ modification + time t them and that end to a 200$ psu of 500W

for that price you can iccasionally get one on ebay that os 750 or 1000W with higher specs! ... and ready to deliver the full power you need without going into overload, overheat etc!

for 130$ more you can get the 1000W brand new or for 50$ more yu can get the 1500W on ebay!

personally over the last 3 years i bought 3 of them that are used.. (the 750W, 1000W and 1500W)

They all work today and have a really great power density! THEY ARE COMPACT SIZE!

exemple:

1000W 48V for 130$ and... MAKE AN OFFER.. ( btw.. the price of shipping is also offered for 30$)

All you need is occasionally go on ebay and search with : meanwell 750 1000 1500

Generally in less than one month you get what you look for

Doc

Hey Doc,

I win the 2 units of the 1000w psu... i bought 2 units to charge at 100v @ 20 amps... according to your estimate ... its approx

i should get about 2400w charge rate Lol

I don't think any wall outlet in my house will let me do that...

I may have to use that zantrax household inverter 4500w continous ... 9000w peak! ... to charge my bike... LOL

is there any way to adjust current in the 1000w units?

correct me if im wrong, but there is no PFC in these models correct?

I dont know if there is a PFC.. did you checked on teh spec sheet?.. if they dont mention it they dont have it.

There is a way to drop the max power limit of them.. but i never tried to. There is a shunt inside on the HV DC section.. you just have to add some turn on the coil.. or to sand the shunt...
 
By the way...
I just used my meanwell today.. the stock fan appears to be dead from the factory.

Thus, i overheated the living daylights out of my meanwell, to the point where it made a buzzing sound and the voltage / current readings went all over the damn place!
I was wondering why the fan wasn't turning on, lol..

Had it set to 41.5v and it jumped itself up to 48v and the current was wavering rapidly from 6.67a to 4.99a

You know what though? i unplugged it, let it rest a bit, put some lipo-powered fans on the thing, and plugged it back in and it worked great.

I dunno about the other variants but the one i got from sureelectronics seems to be very hardy.

I left mine plugged in at 43.5v plugged into my ping pack for 5 or 6hrs. I had fallen asleep and woke up running to my garage and the thing was burping away (cycling between 0 and .5 amps). It looked fine initially, but I tried to use it yesterday and 000000 no go. What the hell?
 
Man I leave mine plugged into my pack days at a time with my medic balancers on. I hear it cycling on ever so often. But its been solid for me. Stock fan is good. I did the always on mod.

There is no AC power to it. What should I test first?
