Product application:
DTSP-40 3P DC SPD 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 commonand different modes protection. Its installed location are recommended at both ends of the dcpower supply line (solar panel side and inverter / converter side), especially if the line routing isexternal and long.High energy MOVs equipped with specific thermal disconnectors and related failure indicators.
