LED power supply surge protector
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. There are two structures：in parallel and 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. For big surge of absorptive capacity,low residual output,compact appearance,optional water-proof structure,easy installation.
