Product introduction 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. Product features 1.Type 2 surge protective device for Photovoltaic. 2.Module design, convenient installation, could be replaced. 3.Time of response <25ns. 4.The color of visible window shows operating status, green means normal, red means abnormal. 5.No leakage, no operating currents. 6.Remote Signaling (option).
