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.

Following in the footsteps of the previous article, let’s look at some tips to prevent the damage to surge protective devices (SPDs). 1. Overvoltage Conditions As surge protective devices (SPDs) break is due to overvoltage conditions, choosing a suitable voltage for the surge protective devices (SPDs) is important. 2. Burn-in of Surge Protective Devices (SPDs) […]
Ylong offers the most comprehensive portfolio of Type 1 and Type 2 surge protective devices that can be externally or internally mounted. They help reduce costly downtime while protecting sensitive electronic equipment against damaging effects of transients caused by lightning, utility load switching, internal load switching, and more.
To protect an electrical installation in a building, simple rules apply for the choice of 1. SPD(s); 2. its protection system. For a power distribution system, the main characteristics used to define the lightning protection system and select a SPD to protect an electrical installation in a building are: 1. SPD 1.1 quantity of SPD 1.2 type 1.3level of exposure […]
