Energizers
energy Smart DUO EDW
with power output higher than 5 J
Standard’s special requirements must be observed for energizers with power output higher
than 5 J, namely time cut-off limit when the power output is increased and thus ensuring
safety.
Products must be identified by mark.
fencee energizers have time cut-off limit of 50 seconds, which means that whilst the fence
system is under load and its resistance drops below 500 Ohm (overgrown grass, fallen branches,
etc.), the energizer will supply the maximum of 5 J for 50 s. If the fence system resistance does
not increase during this time (carrying out corrective measures), the energizer will gradually
increase the power output (e.g.
EDW150
model up to 15 J).
Acoustic and visual warning when the fence system is suddenly under load is another feature.
If the fence resistance drops abruptly during one pulse from over than 1000 Ohm to less than
400 Ohm (fallen branches, tangled animal or human, etc.), alarm is triggered after six pulses,
acoustic warning and red LED indicator light flashes. At the same time, the pulse period is
shortened to 3 s. The alarm is switched off after increasing the fence resistance to more than
600 Ohm or after the time limit of 10 min. Both functions are independent and separate.
