PYRAMID PS14KX - Bench Power Supply, AC-to-DC Power Converter (12 Amp)

The Pyramid PS14KX power supply is just what I need---12 volts at 12 amperes. Actually, 13.8 volts at 12 amperes. The 13.8 volts insures the device I am running receives all the power it requires. The power supply features temperature and overload protection--- valuable insurance against fire. A word of caution: the heat sinks located on the back of the unit get very warm (which is normal), so be sure to keep heat sensitive objects away from the back. Also, there are ventilation holes all over the chassis box. Don't cover the unit with anything which might block this ventilation, as that could cause overheating, and it could shut down. This unit is more a utility power supply, and does not offer elegance---but it suits my application perfectly. One more note: There are two power terminals with black and red nuts to attach the power output cord, so you may need to purchase an adapter to connect it to the device you are running. Make sure you get the polarity correct!

PYRAMID has made Reliable good working power supplies for many years. I have one that is more than 20 years old

The price was the lowest I could find. The best quality low amp power supply on the market.

Perfect power supply for CB/SSB radios.

I bought this for a 12V CB in my house. When using the power supply there is a noticeable hum coming from my CB. It's worse when I transmit. I've never had this problem so I'm thinking it's the power supply. I went out in my Jeep and talked to my wife over it and I can not hear the hum in the transmissions so I'm going to go ahead and keep it. Not sure I would recommend.
