- this kit is basically a filtered and regulated power supply without the transformer. Input voltage up to DC or AC 20V. Output voltage from 1.25V minimum to maximum 3V below the input voltage.?
- a schematic might be added to the manual in the next update.
They gave me the attached schematic.
?
With my three LiFePo batteries connected in series I would get a filtered and regulated voltage from 11.2V (full charge)? to 9.8V (full discharge) or a filtered and regulated 9V (from full charge to full discharge), which would be even better for a QMX+.
With my 5 to 12V-3A and 13.5V to 15V-2.4A Wall Wart set to 15V I would get a filtered regulated 12V-1.5A power supply, set to 12V I would get a fitered regulated 9V-1.5A power supply.
With a computer wall wart delivering 19.5V I would get either a filtered and regulated 12V or 9V.
And it costs 20 US$, I'll think to it if I build a QMX+, it could be inserted in a QRP-Labs "large blank enclosure" with a "dev kit", an AF amplifier and speaker and possibly a 10 W linear amplifier ()...
