Functions and application areas

DC surge protector BY40- PV1000 is suitable for solar photovoltaic system. It is a voltage-limiting surge protector. It is used to prevent lightning overvoltage and transient overvoltage from damage to photovoltaic power generation DC power system. It is used to protect DC power system from overvoltage. Surge protector for solar power. It has positive and negative to ground common mode protection and positive to negative differential mode protection, which can ensure the most suitable lightning protection for DC module inverters. Normal: 1. 3 normally closed, fault: 1. 3 normally open). The salient features of the DC surge protector are low output residual voltage and fast response time, especially when the lightning surge passes through the protector, the subsequent current will not appear. When the lightning arrester fails due to overheating, overcurrent, or breakdown due to lightning strikes, the built-in failure tripping device can automatically disconnect it from the power grid. The product grade is C grade.

Warning

This product does not require daily maintenance, but the lightning protection module needs to be checked regularly every year. If you find that the color of the fault indication window changes from green to red, please contact our company in time, so that our company can handle it in time, relieve your worries, and for your safety Escort.
