Nice Supply, So Far So Good!

I have only used this for a few days but everything appears to work great. I requested a copy of the owner's manual from Voltek through the CHAT! feature and they emailed me a PDF immediately so I was able to review the manual before buying. A few warnings were contained in the manual that I am being careful to follow: 1) Don't turn on or off the supply with a load connected to it, especially if it is an inductive type load. 2) Don't run the supply continuously at max amps and volts (one of these needs to be at 80% or so.) I am mostly working in the 13.8 volt area, so not a problem. Note that the supply DOES NOT come with test leads so you need to order those with the supply. I assumed they came with test leads so I needed to order them after the supply arrived. Recommendation to Volteq: Since many of the supplies have identical owner's manuals, why not have a link on your website where potential buyers can download it?
