Surge protection as solution

A reliable way to increase the outdoor luminaire 
protection against excessive surges is to use the 
Philips Xtreme Surge Protector.  
The Xtreme SPD will limit the differential and 
common mode surge voltage build-up inside the 
luminaire while at the same time offering a diversion 
path with a lower breakdown voltage. The energy of 
the voltage surge is returned as a surge current, via 
the Xtreme  SPD, to ground and eventually back to 
the cloud. As such, it will protect both the driver and 
LED module against damaging surge stress. See 
figure on the left. 

The Xtreme SPD has to be connected to the 
protective earth connection of the luminaire.

Please refer to Electrical design for more
