Why are AC models damaged by lightning more often than battery operated models?
A. Battery operated fence chargers are not connected to AC power lines. Most lightning damage to AC powered fence controllers comes in through the AC power line. The lightning may actually strike a long distance away from the fence charger but is transmitted through the power line and will damage equipment connected to power lines, such as televisions, stereos, fence chargers etc. Parmak AC powered fence chargers are equipped with lightning arresters and a 1 amp fuse (model HS-100 has no external fuses) on the AC line. These lightning arresters help to eliminate much of the lightning damage, however, it is impossible to stop lightning damage 100%. It is recommended whenever possible that the fence charger be disconnected from the AC outlet during electrical storms. We also recommend that you plug your AC fence charger into a surge protector (see information on the Parmak Electro-Gard). The surge protector will give additional protection to your fence charger.
