Noark 1000V DC Surge Arrester DC Surge Protection suitable for PV applications
DC Surge protection devices Ex9UP are suitable for photovoltaic applications. These SPDs are tested according to Class II. Indication unit helps users to know the status of device and remote-signal port is able to provide remote indication and alarm. Plug-in module design make it convenient to change module without device disconnection.
Surge protective devices, are voltage limiting Class II devices which present high impedance when there is no surge, if a surge occurs, the impedance will drop rapidly to limit the voltage at its output terminals to the specified range.
