Surge Protective Devices (SPD)

Electrical events, such as lightning, can couple into metallic conductors and cause damage from the excessive system voltages and currents (surges) generated.

SPD are used to mitigate these coupled surges in both High Voltage (HV) and Low Voltage (LV) power systems and communication systems.

An SPD has a non-linear voltage-current characteristic that reduces voltages exceeding the normal safe system levels by a rapid increase in conducted current.
SPD are also called voltage limiters or overvoltage protectors or (surge) arresters.

 

Applications:

Surge Protection in Industrial electronics, such as:

* industrial electronics,
* telephone and telecommunication systems,
* sutomobile equipments,
* measuring and controller systems,

Features:
Fancy selected components, fit for the poor-quality power network
Special temperature - controlled disconnect technology used in MOV module and GDT module, stand to prevent thoroughly from fire risk
Malfunction alarm (alarm interface), support for remote-montitoring
Translucent indication windows can indicate working state clearly and directly
Integrative design, convenient installation, simple maintenance
