TAXNELE TXSD-PV — DC Surge Protective Device for Solar PV
Surge protective device designed for solar photovoltaic (PV) systems, providing protection against lightning and surge overvoltage. Installed in parallel on DC networks at both ends of the DC power supply line (solar panel side and inverter/converter side), especially recommended for external and long line routing.
Features
- Instantaneous Lightning Protection — Conducts surge overvoltage to earth immediately, protecting electrical equipment
- Visual Indicator Window — Green = normal operation; shows working state at a glance
- PA66 Flame Retardant Housing — Heat resistant, chemical resistant, and ESD protected
- Fast Response < 25ns
- IEC 61643-1 CE Certified
