30V 10A 110V DC Power Supply Precision Variable Digital Adjustable Safe circuit

the same ones on ebay are a little cheaper
you can get a 60V for $70 or a 120V for $90

30V is mostly useless for people testing 36V cobs.

my 120V doesnt even go up to 120 it pusses out around 100
 
I have been curious about this type of power supply as well. I havent seen anyone using them. Check out this grow box and his power supply, pretty cool. Minus the scotch tape. :joint:

correction: im a bonehead and did not check the input voltage switch that was set to 230V by default. once i flipped it to 115V AC it took my 275W cutter cob up to [email protected] (current controlled by cob, coulda probably kicked out the rated 3A at 120V with the right load)

so yeah im pleased with my $95 purchase!
