Type 2 DC surge protection device up to 1000V
Solar DC SPD protects the solar equipments like solar panels and solar inverter from surges damage or overvoltage.
Improve the PV system safety for a longer PV system life.
PV standard EN 50539 and IEC 61643
The DC SPD is developed according to PV standard EN 50539-11 and new standard IEC 61643-31:
Low-voltage surge protective devices-Part 31: Requirements and tests methods for SPDs for photovoltaic applications.
ZJBENY is the first company in China tests the SPD at the PV standard.
Recommend by top solar inverter companies.
Plug-in MOV modules
The surge protection device is consisting of a base part and 3 plug-in high energy MOV protection modules.
Remote signaling contact for monitoring device is for options.
With thermal disconnect mechanical inside for fault indication by red indicator flag.
