Pyramid Heavy-Duty 30 A Fully Regulated Low Ripple Switching DC Power Supply PYRPSV300

Price is the best and the most safety features. Well made and all positive feedback works as it should and beyond.

Well known name in audio %26 amateur radio power supplies. I trust this company. The voltage checked at 13.8 DC. It powered my 50 watt transceiver without struggling. I didn't check the ripple %, but it should test good.

It does the job fan is a little loud

I bought this item to use with a 2m amateur radio that runs off 13.8v DC. Whenever I hit the transmit button and put a load on the power supply it buzzes loudly. This doesnt seem normal, but if it is still a deal breaker because it is so loud. Planning to return and reinvest the money into a higher quality product.

Second one of these. Great for amateur radio. They only funny thing is that the latest one says Pyle and not Pyramid, but it seems to be the same unit.

This is a very affordable and noise-less power supply. No fan noise detected. Clean, reliable power for any 12 volt, 30 amp max project or ham radio equipment need.

I ordered a 50 amp pyramid and then I ordered this 30 amp power supply. the 50 is a piece of junk. put all kinds of bad RF all over my electronic equipment. the 30 amp it works pretty good don't have any trouble with the Rf.

fantastic power supply great voltage I run my Palomar 225 on it and have plenty of juice it makes my Palomar do its full potential great product

This is a great little converter. I work in the rv industry and often times need to simulate 12v power without lugging a car battery around. I have a few models, but this one is quickly becoming my favorite. It's fairly light weight and easy to keep in my work trailer.

I have been testing this power supply for only a few hours, but so far it really works great. It powers my 2-meter ham radio at the 50 watt output power level without any problems. It does not seem to heat up or make any noise that are sometimes a problem with switching power supplies.
