A range of 12V power supplies for operating mobile equipment from the mains.

Most CB's, Amateur radios, and accessories are designed to work off a 12V supply. So in order to use them at home you will need a suitable power supply.

We stock a large range of power supplies from 3A to 40A.  It is important that you choose a suitable size supply for your needs. Buying one smaller is false economy - at best it will not work correctly and at worst you will blow it up and possibly also damage your radio.

As a rough guide to the size of power supply you will need:

3A = 5W,  5A = 30W,  8A = 60W,  10A = 100W,  30A = 200W

Regulated 13.8V power supply, ideal to run any legal CB radio or accessory which requires up to 3A.

"Linear type" (with traditional transformer) means that there is no risk of RF interference from the power supply. The only disadvantage is that it is much heavier than the "switch mode" type.

Current limiting & short circuit protection.

Regulated 13.8V power supply, ideal to run any legal CB radio or accessory which requires up to 3A.

Switch mode design makes it both lighter and more compact than a traditional transformer.

Because these are designed especially for radio use, they include extra filtering to prevent the interference suffered with cheaper switch-mode power supplies.

Current Stock is QJE Brand

Sharman's new LM30 DC regulated Linear power supply has a maximum output of 30A with adjustable voltage output from 1.5V DC to 15V DC, ideal for powering most HF transceivers & high power accessories. Being a traditional transformer type power supply there is no chance of any RF interference that can come from switch mode power supplies. 

It has been designed for various applications, including HAM/Amateur users where reliability, protection and immunity to RF are important.

The power supply has twin analogue meters to show output voltage and output current and has several output connectors for convenience and flexibility. It also has short circuit and current limitation protection.

Our current stock is under the "QJE" brand name, these are exactly the same power supply as the Sharmans just with a different name on them.
