Surge protective device, protect against lightning surge voltages in solar system (photovoltaic power supply system).
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.
High energy MOVs equipped with specific thermal disconnectors and related failure indicators.

 

 

For microwave communication equipment, mobile station communication equipment and radar equipment, such as the use of rectifier power supply, depending on its working voltage protection needs are appropriate to choose the working voltage of the appropriate DC power lightning arrester as the last level of protection.
Fourth level and above
According to the voltage level of the protected equipment, if two levels of lightning protection can be done to limit the voltage below the level of the equipment, only two levels of protection are required, if the level of voltage resistance of the equipment is low, it may require four or more levels of protection. The fourth level of protection whose lightning through-current capacity should not be less than 5KA.

 

 

 

This series of surge protector device(SPD)is suitable for new energy solar power generation system, and the maximum continuous working voltage is DC500V, 800V, 1000V, 1200V. The installation position is in the DC power supply system to protect indirect lightning current, direct lightning current or other transient overvoltage.
