Interested in a Kit of Parts of the Low-Noise Power Supply? Click the button "Back this Project" at the right of this page, in the Jumpstarter column. The price of the kit will be €160.

This fully analogue, adjustable, medium-power symmetrical power supply contains no switching or digital components. It provides an output voltage adjustable between 0 V and ±22 V, and an output current adjustable from 0 A to 1 A. Because it avoids any form of switching circuitry, the design delivers extremely low noise. To display both output voltages and currents, four miniature moving-coil panel meters are used.

This page is a support page for the JumpStarter campaign to measure the interest in a kit of parts. The kit would include:

Not included are:

The reason not to include the transformers is their weight. They would make shipping costs too high as they must be shipped twice: from the supplier to Elektor and then from Elektor to you. This is inefficient and not ecological; it is better for the user to buy his/her own tranformers.

A commercially available enclosure for the Low-Noise Lab Power Supply does not exist. Therefore, it is up to the user to build one. We made one from aluminium plates sourced from an online custom cutting service. You could do the same, or use a suitably-sized commercially available enclosure.
