China ELR2 Series DC Isolator Switch factory and manufacturers

ELR2 Series DC Isolator Switch

Short Description:

ELR2 Series DC Isolator Switch in plastic enclosure is applied to 1-20 KW residential or commercial photovoltaic system, placed 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.
