Manufacturer of Low and Medium Voltage Switchgear

DC Surge Protection Device for PV System

     The products are used in various DC power supply systems, such as background broadcasting systems, communication systems, security monitoring systems, fire control systems, photovoltaic power generation systems, industrial control systems and other DC power supply equipment to protect the equipment power supply system from lightning overvoltage and over-operation. damage from voltage


 High-quality lightning protection chip, high reliability
 Large flow capacity and low residual pressure
 Adopt temperature-controlled circuit breaker technology to avoid fire, and have working fault indication
 With remote alarm contact (at the same time with normally open and normally closed contacts), it is convenient for remote monitoring
 Fast response time, action in nanosecond time
 35mm guide rail design, easy to install
