1. Overview
DC power surge protectors are mainly used for C-level protection of DC power distribution systems. They
are used to protect electrical and electronic equipment from lightning electromagnetic pulse induced voltages,
operating transients and resonance (<100μs) overvoltages. They are widely used in communication equipment,
power protection in electrical, electrical appliances, power equipment, security monitoring, transportation,
industrial control, aviation and other fields. This series of products has the characteristics of extremely fast
response time, built-in thermal protection, low residual voltage, timely tripping, etc., and the flame retardant
level reaches V-0 level, which can prevent fires to the greatest extent and provide safety protection.
2. Safety guide
Only professional and technical personnel are allowed to install, maintain and replace lightning protection
products according to this manual.
Installation must be carried out in the case of power failure.
Please check the working status of the lightning arrester regularly, and replace it in time if the lightning
Surge protector and circuit breaker should keep a distance of 3-18cm.
