Hi
I am looking to finalise a project I have stalled for quite some time.
I have a vehicle that when garaged it connected to a charger (24 Volt)
The requirement is that I am able to maintain charge for a tablet and a couple of radios whilst its garaged.
I have a 240v/12-volt transformer that gets plugged in at the same time as the 24v truck charger
At this point, the truck is electrically isolated by a big kill switch which allows you to plug in the 24-volt charger.
When the truck is about to go out its unplugged from these two independent power supplies, the kill switch is turned off and the truck can start.
The radios have a 24v to a 12volt transformer which has ample capacity to also supply the 12-volt circuit for the tablet.
Max peak power is 10 amps
I am told I need a DPDT relay to achieve this.
I have had a look around the web and see more lots of wiring diagrams for dpdt but it seems that I want the reverse of all the examples seen so far.
As I want two inputs to supply one output.
So my goal is no matter what configuration the truck is in either operational or garaged I want to constantly feed power to the tablet and radios.
Can someone assist with a DPDT wiring example that fits the bill and hopefully an example part number so I can get the correct one.
Thanks & Regards
Jason
