Blitzschutz

Lightning Arrester Application range: LDY-C/DB9 SPD are applied to the equipment for surge protection with DB9 interface, which can prevent the signal equipment from the permanent damage or transient interruption arising from inductive overvoltage, overcurrent and the other transient surge voltage caused by lightning or industrial noise, etc. (Option from standard IEC61643-21 and GB50343). Main feature: Convenient for installation for replacement, standard DB9 interface;Choosing the latest high-speed surge protection component, quick response, low output residual voltage and super transmission performance;Small volume, exquisite, strong applicability.

The SPD is connected in series between the signal channel and the protected equipment.2. The SPD is needless for special maintenance. When it is suspicious of SPD fault in system operation, please dismantle SPD module and then check. If the system recovers normality, SPD has broken down and needs replacement. During replacing SPD module, circuit will not be cut off and be in normal working.
