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 limiting & short circuit protection.

Regulated 13.8V power supply, ideal to run a higher power CB radio or accessory which requires up to 5A.

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 limiting & short circuit protection.

The PS-30M 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 analog 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.

Sharman's 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 digital 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.

QJE QJ1840SC DC regulated Linear power supply has a maximum output of 40A 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.

A very compact switch-mode power supply suitable for many HF radios and amplifiers that require up to 23A.

This psu is designed to supply a maximum of 23A with a fixed 13.8V output.

The main output terminals are on the rear, but it also has a standard cig lighter socket on the front.

A compact switch-mode power supply with a large analogue meter and variable voltage. The meter can be selected to read either output voltage or current.

This psu is designed to supply a maximum of 30A.  There is also an adjustable "noise offset" to eliminate any RF noise caused by the switch mode supply.

The voltage can be either variable or fixed.

A compact switch-mode power supply with a large analogue meter and variable voltage. The meter can be selected to read either output voltage or current.

This psu is designed to supply a maximum of 50A.  There is also an adjustable "noise offset" to eliminate any RF noise caused by the switch mode supply.

The main power outlet connectors are on the back, with a standard cig lighter socket on the front.

The voltage can be either variable or fixed.
