This is a Top Quality MGG Pro Series energiser (TWO YEAR WARRANTY) which will power up to 50Km of single wire fence or 20Km for a 3 wire fence. For battery use, it can be installed outside in the weather but for mains use must be installed indoors.
Dual voltage is a great benefit because if you get a power cut you can easily switch to a car battery until the mains is back on again. You can also easily convert to solar power if required by adding a solar controller and panel to your 12v battery. It delivers 4 joules, 9500 volts and consumes just 4.8 watts.
Supplied complete with Mains adapter, 12v DC connection cables and lead-out cables and clips for your fence and earth.
