Scope of Application
The SPD dedicated backup protector, provide power supply with 1,2,3 equipment to protect the
SPD(lightning protector) professional backup protection, is suitable for the need to install the
SPD lightning protection devices, such as: civil construction, electrical, communications, road
traffic, such as the petrochemical industry of power equipment.
Product Usage
It is effective to protect the SPD from the occurrence of abnormal transient overcurrent, so as to avoid serious fire accidents.
The actual selective separation of the working frequency current and lightning current can
effectively protect the SPD from the occurrence of degradation, which can reduce the starting
voltage of the SPD to a lower than that of the power supply voltage, so as to avoid causing
serious problems. Fire accident.
When the SPD has an outdated lightning flow, this external disconnection will not cause an
error trip, so that the lightning protection of electrical equipment is always in an effective state.
