CNKA dc lightning surge arrester Introduction

 

China suppliers CNKA offer affordable DC lightning surge arresters made in China. It is recommended to use DC lightning surge arresters at both ends of the DC power line (solar panel side and inverter/converter side), especially when the line wiring is external and long. The ESP-D40 DC series features a circuit design based on high-energy MOVs, equipped with specific thermal isolation switches and related fault indicators, providing reliable surge protection. This ESP-D40 series also includes a remote signal function, allowing users to monitor device operation in real-time. Additionally, the ESP-D40 DC series employs a plug-in module design, enabling quick and convenient maintenance in the event of a malfunction.

CNKA dc lightning surge arrester FAQ

 

Q: How does a solar surge protector work?

A: A surge protector serves as a safeguard against electronics damage by redirecting excess electricity from the "hot" power line into a grounding wire. This is accomplished using a metal oxide varistor (MOV) in most standard surge protectors, which consists of a metal oxide linked to the power and grounding lines through two semiconductors.

Q: What are surge protection devices for PV?

A: In order to ensure the safety and protection of both household and large-scale PV installations, it is important to adhere to specific design protocols. Key measures such as the installation of lightning arresters and surge protection devices (SPDs) should be implemented to proactively safeguard the system and prepare for potential power surges.
