Review on 12V 30A Universal Regulated Switching Power Supply Driver: Ideal for LED Strip Lights, CCTV, Radio, Computer Projects - Padarsey by Jim Agosta

GOOD: Price is of course the main selling point, this PS is very durable and well made. Voltage and current are stable even under heavy load, fan noise on a scale of 1 to 10, I would say 5, connection points for input/output are solid BAD: if you use this power supply for amateur radio or CB radio, you must have one Noise filtering system can be built or purchased, the power supply does not cause much interference on 40cb channels, although it is still a little noticeable. BUT at lower HF frequencies there are large variations in some ranges. I made a ferrite choke, installed it on the + output to my RF setup and it helped a lot but is still noticeable. Overall this is a great stock for the price and with a few bucks more and a little effort you can add some ferrite and help it a lot.
