can we use Telecom DC power supply to supply RB1200 ? like RB800-RB600.

we have issue on power 220V but the 48V its stable.

Ahmed.

the case contains a PSU with 110/220V input and 12V output. The board itself accepts 12-24V. You can replace the built in PSU to a different type of PSU if it outputs 12-24V

Power jack: 12-24VDC
IEC C14 jack: 110-220VDC

RouterBOARD 1200 power technical specification from User Guide,
http://routerboard.com/RB1200

Is this 12-24V absolute rating for the RB1200, or is it reasonably safe to go a little below 12V or above 24V? Some other routerboards were specified for a wider range like 8-30V.
I'd like to use a lead-acid battery backup power supply, either 12V or 24V one, as a more efficient alternative to UPS. This means either 10-14V or 20-28V range (low battery cut off to fully charged), both a bit outside the 12-24V spec. Will the RB1200 run down to 10V, or up to 28V with no damage - or is that too risky? Similar issue with your competitors radios, specified for 12-24V too - but my tests confirm they still work at 10V PoE over 20m of good cat5e FTP, wasn't brave enough to try if they survive 28V though.

It should accept 10-28V range, but there is no overvoltage protection so careful not to burn it. (30V can damage it)

I'ts so funny production in the 2011 year. Whay not make overvoltage protection?Lower cost routerboard 411&433 use feature.

we make two models. cheaper, and better. choose RB1200 or RB1100 depending on features vs price.
