what precision volts RB1000, this is works in volts the 12v at 48v?
This show only title datasheet 12v,
In rb433 used 12v at 48v…
What volts I can used in me RB1000?
I think it is 12-28V
And RB433 runs on the same…
12V and ONLY that
You mean 12V like recommended, but 10-28V is possible use if customer replace according CPU fan. Fan voltage=Input voltage
I pretender used in Batery of car, this have 13,4v more ocilant at 11,1v. I like know if I can used this batery ofcar in my RB1000?
You have gigabit network on your car?! Of course you can use 11,1V likewise 13,4V but I not sure that RB not reboot when you start engine 
)
If you not help… then you silent ok…
I like know if used the batery of car… off course what not used RB1000 in car… I aliment power the RB 1000 with batery of car…
