Default RE: Mean Well power supply

Per Greg E....... I bought the Meanwell 11 Amp 27 Volt unit at JameCo for the $70 price..... + shipping.

I had trouble snapping off the terminal plastic cover needed to protect the hot 110v contacts....
Plastic cover removes easily if you roll it from the top down...... Snaps on super quick.

I plan to use the Meanwell with the RC (radio Control) mode setup with the Bridgewerks UR-15 DC track feed.

Doing garden bulb/tuber work over the past 5 days & trains are both parked & blocked... in GBay, WI... (5-0 Country..)

or you build your own powerpack.

add a rheostat and you are ready to run.

i just did that, and i am content with two new 24 Volt 15 Amp DC powerpacks.

Gregg -

The "preferred" Meanwell supply depends a bit on the application, ie the voltage you want for the device that you're powering.
The one linked to above has a nominal 27 volt output which is adjustable from 26 to 32 volts and it provides an output current of up to 11 amps.
I tend to go for the 24 volt version where the output is adjustable from 20 to 26.4 volts and you get a bit more current - 12.5 amps.
All depends what you are driving with that supply.
I also tend to go for the PFC version of the Meanwell which is a bit more money but it saves a bit of money in the long run. Not sure it makes total financial sense from a payback perspective since we don't run our trains for long periods every day but it's definitely more environmentally frindly.

The reason I have recommended the 27 volt one is for DCC where 27 volts input normally yields 24 volts to the rails, helpful in many DCC situations.

Also, the NCE system I use is a 10 amp system, so over 10 amps is basically wasted.

Regards, Greg

Yes - for your application (powering the NCE DCC system) the 27 volt version makes sense and is the correct one to chose.

I used my first Meanwells with a home-brew analogue throttle which had a fairly low voltage drop at maximum and for that application even the 24 volt unit provided more voltage than what I needed.

But since I'm going to use that supply in the future, I decided not to go with a lower voltage which I could have done for that initial analogue use.

Is it safe to use a Mean Well power supply with an LGB throttle, such as the 51070, 51079, 52120 or 52121? Reason I ask is that I have read that using an LGB throttle with a non-LGB power supply may cause the short circuit protection to fail.

Also, with a Mean Well power supply and an LGB throttle, would you get pure DC or pulse power?

Dude, you really need to make a new thread instead of jumping on an 8 year old one.


Next, you do not post the same question in several places, one place is enough.


I answered you on the slightly newer thread.
