Hi,
I have this assignment for a Diploma I am studying and I'm a little stumped. I feel like the method to working it out is right in front of my face but for some reason I can't see it. Here is what it says in the assignment:
------------
The Radio system will be powered by a D.C. Power Supply, with built-in Back-Up Battery facility. The Power supply is rated at 13.8 V, 25A 100% Duty Cycle.
The Radio System consumes 650 mA when quiescent; 1.75 A when receiving, and 7.75 A when Transmitting. The Duty cycle of the Radio is 40% quiescent, 30% Receive, and 30% Transmit.
There is a 12 V, 50 AH Battery connected to the Power Supply. The client needs 30 Hours of operating time in the event of a mains fail.
-------------
The assignment lacks a lot of direction however I assume that it wants me to work out if a 50AH battery will provide 30 hours of backup and then provide a solution.
I've done a heap of things to try and work it out but I'm not confident in any of it. If someone could point me in the right direction that would be awesome.
