Application
L1 Series DC Isolator Switch is applied to 1-20KW residential or commercial photovoltaic system, pleced between photovoltage modules and inverters. Arcing time is less than 8ms, that keeps solar system more safe. To ensure its stability and long service life, our products are made by components with optimum quality. Max voltage is up to 1200V DC. It holds a safe lead among similar products.

The main objective of the electrical installation protection system is to limit overvoltages to values that are acceptable for the equipment. The electrical installation protection system consists of: =one or more SPDs depending on the building configuration; =the equipotential bonding: metallic mesh of exposed conductive parts. Implementation The procedure to protect the electrical and electronic […]
SPDis an indispensable device in the lightning protection of electronic equipment. Its function is to limit the instantaneous overvoltage entering the power line and signal transmission line within the voltage range that the equipment or system can withstand, or to discharge the strong lightning current into the ground. , to protect the protected equipment or […]
In spite of the high lightning risk that many PV installations are exposed to, they can be protected by the application of DC SPDs and a properly engineered lightning protection system. Effective DC SPD implementation should include the following considerations: •Correct placement in the system •Termination requirements •Proper grounding and bonding of the equipment-ground system […]
