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.
