What does 240AC/12DC Volt Mean

In every active explorer Caravan Antenna System you get a power supply that allows you to run your Antenna on either the normal power point (240 volts) or a separate DC lead is included so you can run your antenna from a solar battery or any other 12 volt DC source.

A couple of explanations as this is an area of great confusion. Everyone these days has a mobile phone. When you plug your charger into the powerpoint, in Australia, that delivers 240 volts to the unit.

Within the unit that you plug in there is a device such as a transformer . The Transformer or other device is used to change the incoming voltage to something else. The voltage that actually goes to your phone is likely to be 5 or 6 volts only, It is also converted to DC (Direct Voltage). So the voltage is stepped down to something much lower. Voltage is just a quantity of energy

The explorer power supply has a transformer in it too! The power starts at 240 when you plug it into the electrical socket but the inbuilt transformer reduces it to 12 volts and it is converted to DC.

So the antenna requires 12 volts DC only whether it is supplied via a power supply plugged into 240 volts or a cable that is plugged into a battery or solar panel.
