surge protector DC

surge protector photovoltaic power system surge protection device LT-S40 DC 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. LT-S40 DC is module design, with the characteristics of fast and easy maintenance in case of failure (disconnection from the DC network). LT-S40 DC series are available for the network voltage: 500,800 and 1000Vdc.
