Be careful the power supply you get does not create EMI or RF interference noise ... it will kill the signal

Friends, 

I just received my HF preselector. It included a power connector cable without power supply. The connector is either not the correct size, or it is really, really tight, so I have not tried to force it on. In any case, reading the specs on the CCW web site, it appears the unit needs  12 mA from a 12 - 15V DC supply. Does anyone in the group (preferably a user in the United States) have a recommendation on what to purchase, assuming a power supply is required? My simple searches for a power supply that meets the specs produced no results. The best I can come up with is something like this: https://www.amazon.com/SoulBay-Universal-Switching-Selectable-Suitable/dp/B01ISM267G/ref=pd_sbs_23_4/147-2735014-2765860?_encoding=UTF8&pd_rd_i=B01ISM267G&pd_rd_r=02405990-d5c9-415e-82f6-28a632491675&pd_rd_w=iT2GV&pd_rd_wg=hPAYK&pf_rd_p=7cd8f929-4345-4bf2-a554-7d7588b3dd5f&pf_rd_r=1AXDK9399SAF9C117RBF&psc=1&refRID=1AXDK9399SAF9C117RBF

and it has an output of 1.2 amps, well above 12mA.

Suggestions? Many Thanks all. you.
