The use of light-emitting diodes (LEDs)
and electronics in lighting equipment
has highlighted the problem of excessive
voltage caused by direct or indirect
electrical charges. In the cases studied
80% of damage refer to improper/abnormal
feeding.
These problems may arise from:
- disturbances inherent in the electricity
mains; insertion or removal of strongly
reactive charges, faults in the cables, or a
strong harmonic distortion in the mains;
- excessive charges arising from the
environment: direct or indirect atmospheric
discharges or unexpected and excessive

accumulation of electrostatic charges on

ARES offers an SPD (Surge Protector
Device) which can be connected near the
appliances requiring protection or above
the derivation box.
This device functions in common and
differential manner at the same time,
by absorbing any excessive voltage and
discharging it, depending on its nature,
towards earth or neutral.
The closer it is installed to the appliances
requiring protection, the more effective
this type of protection is, and it should be
remembered that an earth connection is
needed to protect the appliance effectively.
ARES shall not be held liable for the installation of plants not complying with the regulation in force.
