MATPH
Lightning Surge Protectors for
Electronics Equipment M-RESTER
SURGE PROTECTOR FOR PHOTOVOLTAIC SYSTEM
(750V DC,1000V DC USE)
Functions & Features
• Surge protection for photovoltaic array and power conditioner.
• High discharge current capacity 20 kA
• Degraded head element is automatically separated from the power lines by the incorporated thermal breaker, and the LED lamp (turns off) and the relay contact alerts the failure status.
• Breakdown of the surge protector remotely detected with the alarm output
• Photovoltaic system's resistance to earth is measurable without removing the SPD due to spark gap employed between line and earth.
