Etek DC 2P Surge Protection Device

PV SPD is DC surge protector specially designed for photovoltaic power supply systems.These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection. Its installed location are recommended at both ends of the DC power supply line (solar panel side and inverter/converter side), especially if the line routing is external and long.


Etek DC 2P Surge Protection Device

The function of lightning and surge protection systems is to protect the devices, functional isolations and overvoltage-sensitive consumer equipment of energy distribution systems against all lightning and overvoltage damages. whole building; the outdoor lightning protection system is generally not sufficient to eliminate such malfunctions. At most of types, the defected protection device can be made operative again by changing the damaged insert; these variants are also equipped with both optical operation signal and auxiliary status contact.

More Information

What does a Surge Protection Device do?

A surge protective device (SPD) is designed to protect electrical systems and equipment from surge events by limiting transient voltages and diverting surge currents. Surges can originate externally, most intensely by lightning, or internally by the switching of electrical loads.

Do I need a Surge Protection Device?

Additionally, any commercial, industrial, or public building that is supplied by overhead lines requires surge protection – so the majority of buildings will require surge protection. Residential properties will depend on use and occupancy levels.
