I haven't used that model, but I did have a meanwell power supply once with a jumper to select 240v vs 120v, and it came as 240v by default. When set to the wrong input voltage, it did turn on, but put out the wrong DC voltage and an internal breaker would trip at the drop of a hat.

Subject: [AFMUG] I must be doing something wrong...

So I ordered two of the meanwell DRP-48-24's from two different vendors... Hooked both of them up to AC. They _Both_ sit there and pulse the DC out light and only output 20V unloaded and about 16 loaded with the output looking like it's switching on and off. So I am telling myself the odds are long that I got two bad ones and it's probably something I'm not doing right. Not enough load? Need a battery in the load? Anyone have any help here or is really two of them that are both bad? input is connected to line correctly, verified with volt/ohm meter. output is just an inline volt/current meter into a routerboard.. only about 4 watts on the output...

I am just about to send one back to taiwan and want to find out before they say back to me "Stupid American"
