DC SURGE PROTECTOR
33
EDPG40-3R Surge Protection Device
EDPG40 series surge protectors belong to the DC side lightning arrester of T2 PV
system. When the system has overvoltage due to lightning strike or other reasons,
the protector immediately turns on in nanoseconds to introduce the overvoltage
into the earth for discharge, so as to protect the equipment on the power grid.
Product Application
Product Benefits
No need to consider the load current, plug design, can be replaced live, easy to
maintain.
Internal steal temperature control circuit breaker technology, high safety
performance, no freewheeling.
Green indicates normal, red indicates fault, prompt replacement, clear and easy
to distinguish.
Remote monitoring interface (dry contact) is provided to realize remote
monitoring of working status.
