MD1-PV1000 光伏直流浪涌保护器 创造卓越，追求顾客满意
Create Excellence, The Pursuit Of Customer Satisfaction
Photovoltaic DC surge protector

概述 Overview

MD1-PV1000 系列 C 级电涌保护器适用于光伏发电系统，当系统因雷击或其他原因出现电
涌过电压时，保护器立即在纳秒级时间内迅速导通，将电涌过电压引入大地，从而保护点网
上的用电设备。
MD1-PV1000 系列为插拔式结构，模块失效后可快速更换；防雷模块失效后，指示窗口颜色
由绿色转为红色，同时发送报警信号至连接在产品遥信端子上的远程报警设备。
The MD1-PV1000 series C-class surge protector is suitable for photovoltaic power
generation systems. When the system has a surge overvoltage due to lightning strikes or
other reasons, the protector immediately turns on in the nanosecond time to introduce the
surge overvoltage into the earth. In order to protect the electrical equipment on the point
network.
The MD1-PV1000 series is a plug-in type structure, which can be quickly replaced after
the module fails. After the lightning protection module fails, the color of the indication
window changes from green to red, and an alarm signal is sent to the remote alarm device
connected to the product remote communication terminal.
