Adjustable AC-DC converter to 5-9 V

vitaly

Hello,

I'm looking for an AC-DC converter from 220V to adjustable value from 5 to 9V. Can someone suggest one?

Thanks in advance!

    Hi,

    The enclosed supplies with mains connector and DC barrel connector tend to only be built for a specific voltage, they are not adjustable. (There are some that are switched between different voltages and sometimes come with a choice of barrel connectors, but they are cheap consumer items, not very good usually). The uncased modules are sometimes adjustable,but only in a very limited range, to fine-tune, using a trimmer resistor, not designed for regular adjustment.

    It's recommended to just buy a few enclosed supplies , like 5V, 7.5V and 9V, or otherwise get a bench power supply intended for electronics design, which will be adjustable by nature, in fractions of a volt.
