Power Consumption
idahowayne:
Am trying to decide between the OBi 100 and the OBi 200. We live off grid (solar power only) so I will be running the OBi straight from 12 volts without the power adapter.
I have been told that the OBi100 draws 95 milliamps at idle and 150 milliamps while talking. I would like to know what the 200 draws for comparison. If it is the same or close I would prefer the 200.
Thanks in advance for any info you can provide.

I cannot help you with the current draw from these devices but I have some recommendations for you. The 12V must be regulated. The Obi expects 12V not 14-15V lead acid batteries could supply. Also, you need a fuse in series with the 12V to the Obi for your setup. There must be a way to limit the current should some kind of short occur in the Obi.

OBi200 needs 110-120 milliamps while idle and 160 milliamps while talking.

Thank you support. How about the 202, does it draw any more current than the 200?

Would this simple approach work? 12V zeners are quite inexpensive.
