💡 Tripp Lite PR-3UL DC Power Supply - 3A 120V AC Input to 13.8V DC Output (UL Certified) Review

Not sure if I bought mine from this seller or not. or side CB radio to base station. I plan to use it when it's my only way of communicating with others. When the internet is down etc. I usually play in the side band and don't listen to a lot of people these days. But in an emergency it will be great.

Tripp Lite PR3/UL 3A DC Power Supply, 120VAC Input to 13.8VDC Output This power supply is shipped with the isolation nuts for the connectors missing. In my case it wasn't significant since I throw them away anyway, but it does indicate the lack of quality control of Tripp Lite. The unit works well and provides a stable 13 volt DC power supply. Works well with the low-interference RFID electronic readers I use.

Highly adjustable 13.8v output. Use it for radio and projects. overcurrent protection. Bought mine from a radio station in New York a few months ago and it still works. It fueled my CB, college mockup projects and DCC model trains. Charging mobile phones and the like with 12 volts. I only paid €18.95 back then, but that was enough so far. The device is linear with a transformer and will NOT switch. Very clean HF.

My PR-3UL was made in 1987, I bought it cheap at a flea market probably 10 years ago. The design is a simple inline design with a 2N3055 transistor mounted on a large rear heatsink for the final output stage, so it should be able to source a full 3A of continuous current. Internally it has one Fuse on AC low voltage side. The output voltage has dropped slightly after so many years of operation at 14V instead of 13.8V, which is not bad for all the time. There is a POT that I used to set the…
