China Aidun Electrical produce “SOLARSON” brand SST40-1000 1000V DC surge protective device Type II 2P (DC SPD) are used for solar PV system.
Product description
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.
This product accourding to IEC66143-1/EN61643-11.
