Hi All

I recently moved to the US and have brought with me a SEC 1223 Switch
Mode Power Supply (spec is below). It is not marked up that it can run
using 120V but i tried it and it seems to be putting out about 13.2V on
my meter. I have not stress tested it with a radio connected on
transmit.

Any thoughts?


Regards

Andy

SEC-1223 SEC 23A 13.8V Switch Mode Power Supply * Input 230V AC * Output
13.8V DC * Output current 23A continuous (25A peak) * Thermostatic Fan
cooled * HF & VHF filtering *

The SEC-1223 switch mode power supply offers 23A of continuous current
output and 25A peak. This is more than enough for any 100W transceiver.
Designed with RF operation in mind, it is totally noise free and utterly
stable. Lighter than an IC-706 and bout the same size, it will fit
underneath for desktop operation. It will also fit in a brief case or
flight bag.


Some of these newer supplies can auto switch between input voltage. The
nomenclature on the spec tage will say something like....

" 90~250v "

If it says that, it's a auto switching input
