ref LPS155-C no?? 24v 4.5amps i thinf it's ok....

[bvillersjr]

I apologize, I did not see the second page of the document. The LPS155-C claims to handle 4.5amps and offers ripple, over-volt etc.. Sure seems expensive though. Have you discovered a good deal on it?

Yes, it the 155C, i can have it for 35€
Its this model : http://de.rs-online.com/web/search/searchBrowseAction.html?method=searchProducts&searchTerm=LPS155-C

I've seen others : http://www.lambdapower.com/ftp/Specs/Jws150_Spc.pdf for 30€

And : http://cgi.ebay.fr/alimentation-supply-24V-4-5A-Mean-Well-S-100_W0QQitemZ400082901873QQihZ027QQcategoryZ118515QQcmdZViewItemQQ_trksidZp4340.m444QQ_trkparmsZalgo%3DCRX%26its%3DC%252BS%26itu%3DSI%252BUA%252BLM%252BLA%26otn%3D5%26ps%3D63

I have to choose one of them ...

I think the three can be ok, but i prefer ask to u in order to keep money for other parts of the sim

Thanks

Take a look at this one:

should work fine.

Hi,

I just ordered a 24V 14.6A PSU to connect my SCN5's ...

Is it too much amps?? Does the PSU should normally provide the 4 needed amps ?

Maybe I ordered too fast ... ?

Thanks!

No problem. You may get a problem when connecting a PSU with too much volts, but you'll never get one with too much amps. A motor or light bulb which is connected to a PSU only "pulls" the amps it needs for maximum torque/light.

Measure the resistance of your motor (lets say 6 ohm) and you know how much amps that motor will need. And it will never pull more amps out of a PSU.

U/R=I -> 24V/6ohm=4amps

Thx Jay!!

I am looking to run 3 SNC 6s. Can anyone suggest a specific power supply? I believe these actuators draw up to 9 amps. Please bear in mind the following requirements too:

- stabilised 24VDC
- overvoltage protected
- soft-start

A European supplier would be easiest.

What about using the 24v rail out of a computer PSU? Has this been discussed? Not the laptop black bricks of course but the ATX psu's.

Cheers,

Computer PSU's don't have 24V rails.

Just search ebay for 24V power supply and you will find a boatload with different amp ratings. PSU's these days will work 100V-240V around the world, the plug is the only difference.

Thanks, Frakk, for my on-going education. I guess I got idea reading or misreading an article which stated +12 and -12v somehow made up 24volts.

How do I tell if a 24v psu's going to have "soft-start"? What terms should I be looking for in the data sheets?

Is this a good candidate?
