Hi list,
I bought a USB connected logic analyzer for too much money (not that
much). When buying, I did a mistake and not thought through the
issues, and bought from a US supplier without telling them this needs
to be a 220V country. As a result, I got an external power supply that
is 110V, which outputs 12V AC at 1000mA (why they do not write "1A", I
do not know).
To my shame, I actually bought a universal DC supply without noticing
that it's AC I need, and started a support call with the company. They
were very nice, and when we, finally, found out the source (I hope it
is it), the guy said I could probably get by with 18VDC, but it would
strain the capacitors (my math suggests that 15VDC is closer to the mark).
So, does anyone know where I can get a 12V AC power supply? They are
not exactly a commodity.ji.ac.il/mailman/listinfo/linux-il
first, make sure it will work with 50Hz ( instead of 60Hz)
you can take a 1000ma (or more) low end power supply
( the heavy ones, with lots of copper inside)
open it up, and remove a small electric circuit with diodes and capacitor(s)
connect the 2 wires from the coil to the output.
Alon.
