The Druid 18 LCD is a powerful version of the Druid 15 LCD, boasting 7.2 output Joules into 500 Ohm load.This intelligent unit is the ideal choice for large series security fencing systems. Using the Adaptive Power Technology (APT), pioneered and patented by Nemtek,this energizer offers a new and unique method in detecting how much power a fence can accept and handle before it starts to arc and waste energy,thus maximising the power on the fence. Changes in the surrounding environment can affect a fences efficiency.The APT actively analyses the fence and adapts the transfer of power as required to ensure maximum performance. These Nemtek energizers are an excellent choice for coastal areas,where the salt build-up during the dry season can result in increased power losses along the fence.
