The EMS monitors the power, and if the power is not good, it kills all 120v power to your RV. When the good power is restored, it waits a period (15 seconds or 136 seconds) and allows power back into the RV.

Are these a good idea for a travel trailer? I don't have a ton of electronic stuff in mine, the fridge, 12 volt TV, DVD player, water pump, and the converter......
They are a very good idea for ANY RV that plugs into power anywhere but at your house. All of the devices you mentioned above except for the water pump have electronic control boards. However, if the TV is truly 12v, and not plugged into 120v in any way, it is probably safe.
