Application

ADELS L2 Series DC Isolator Switch 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 comp orients with optimum quality. Max voltage is up to 1200V DC. It holds a safe lead among similar products.
