You have checked that you really are feeding with 120 VAC, right?

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"
