RE: [APML] ST4 power requirements???

["Scott Hammonds" <shammonds@creatorsview.com>]

Thanks Guys. I put in a call to Alan Holmes at SBIG around the same time I
sent the original post and he confirmed the 1 amp about an hour ago.  

Now, how about an answer to this question. Does anyone have any ideas if it
will cause problems to run my ST4 and the Kendrick dew heaters on the same
12v 5 amp power supply? I plan to run my mount on a separate 12v 5a power
supply.

Thanks

Hi Scott--I see you've gotten lots of responses on this question.
I stuck an ammeter in series with the battery power lead on my ST4 a few
years ago. When the peltier was running at  full warp speed trying to cool
the chip down, it was 1 amp, but once it reached temperature it dropped down
to about 750 mA.  So, the peak current is one amp, but your average drain
might be less if you have cool nights--say like Dominic!
