Features:
High energy varistors
Ucpv 1500V.
Fault display and remote alarm function
High energy varistors.
The current capacity is 6.25kA with 10/350μs waveform
Application:
Mainly used in the solar photovoltaic power generation DC junction box, the generated solar cell photovoltaic module surge or light is protected by lightning, so as to protect the solar photovoltaic module panel.
Used for surge protection of electrical components in any other DC circuit.
Surge protectors for solar power generation systems
It is suitable for surge protection of DC power supply line equipment of solar power generation system.
Installation and maintenance：
Installed in parallel at the interface of LPZ1 zone and subsequent zones: power controller, power converter, etc.
When the surge arrester is installed under the required conditions, it does not require long-term maintenance, but only routine maintenance. If the color of the visible alarm window changes to red (fault) during use, it indicates that the surge protector is damaged and needs to be repaired or replaced.
