This product is used for the LED lamps and lanterns of protection and lightning surge pulse.Due to the LED lamps and lanterns for the core of the device is a semiconductor diode,ability is extremely low,even overvoltage,5-6V is enough to destroy the light bead,so you need to select special lightning protection device for the LED power supply lines to surge overvoltage protection,avoid large area caused by lighting strike the same region,the situation of the LED lamps and the lanterns of the black light,the company developed product has the following characteristics :
1. This product is in series.series connection type timely diagnose working state of the lightning protection and change in time so as not to cause secondary lightning lamps;
2. It has large absorption capacity for surge, low output residual voltage, compact appearance, optional waterproof structure, and easy installation.

1） When the voltage parameters of the protector does not match the equipment operating parameter,it may affect the work of circuit. It is recommended to determine the device operating voltage when selecting.
2） Because the protector is installed in series, for some relatively large power devices, other operating currents should also be determined.
3) Plug the power phase line (L) and null line (N)into corresponding connector of the electric surge protector and make sure it's firm and reliable. Connect the ground terminal of arrester with the ground lead of lightning protection appropriately (recommended earth resistance ≤4Ω).
