Triple Protection Using XP2
Led luminaires can be sensitive to power line surges. As such, Garden Light LED has come out with a new transformer that adds another layer of protection to their LED luminaires. All Garden Light LED luminaires come with an integrated surge protection device built into each driver. This surge protector in the driver creates one layer of surge protection. A second layer of protection is available using a Garden Light LED protection kit. This is another surge protector that can be attached to the output (secondary) of the Landscape Lighting Transformer. The new transformer (XP2) adds a third layer of protection to the primary side of the landscape transformer.
When a surge occurs in a triple protected system, the energy present in the actual surge event is dissipated first by the primary side protection (XP2), then by the secondary side LED protection kit, and finally any remnants of the surge that are not dissipated in the actual transformer are then distributed amongst all the drivers for the installed luminaires. Of course all things have limitations. A triple layer protection installation cannot withstand a direct lightning strike but for the bulk of the surges that an installation may see, a triple layer protection system will typically protect the luminaires from damage. Both the XP2 transformer and the LED protection kit are designed to short circuit when exposed to a surge event that exceeds their capacities. These are installer serviceable components and will create opportunities for service calls for their replacement. These are the sacrificial components in the system used to protect the luminaires from voltage surges.
