Have bought a 19"LCD tv for camper. It has a 230 vac in and 12 vdc out power supply rectifier I suppose.
I am worried about when the battery on the camper gets flat and the tv could get unstable votage.
Which of the 2 options should I use
1. Run power supply from inverter in bus when input volts gets down it squeals and if left shuts down.
2. Connect tv direct to on-board 12 vdc battery and monitor with voltmeter.
Thanks for any help.
