Its slightly off-topic (weather automation?) but I'm betting this group
has got some ideas for me!

I'm looking for a 12V power supply (currently using a plug-top 12V
switched 1 amp) that is "grounded" through the t  the equipment.
The
weather station I have (Peet Bros Ultimeter 2000) requires an earthed
power supply in order t  leak the static build up from the anemometer.

Unfortunately, the one I got from Maplins is not and right now after
about 5 minutes, the protection device in the junction box activates and
the display zero's out. If I remove the anemometer for 5-10 minutes I
can then plug it back in and get readings for a short while.

Nowhere can I find a mains transformer that appears t  do what I need. I
was given the suggestion by the American company t  run a wire from the
negative side of the 12V output directly t  earth but I'm not sure if
this is okay for a switched power supply or even if it should be done in
the UK.

So, any advise would be appreciated!

Jonathan
