GENERAL INFORMATION
l Two-module/ Three-module varistor photovoltaic surge protective device (PV DC SPD)
l Visual indication and optional remote contact signaling(S) for use in the DC side of PV systems.
l The Prewired complete unit consisting of a base part and replaceable plug-in protection modules.
l In case of insulation faults in the generator circuit, a raliable and tested fault-resistant Y MOV circuit prevents damage to the surge protective devices.
l DIN rail installation.
SPECIFICATIONS
l SPD according to EN 61643-11/IEC 61643-11: Type 2 / Class Ⅱ
l Max. continuous operating voltage (d.c.) (Uc): 12Vdc~1500Vdc
l Nominal discharge current (8/20µs) (In): 20kA
l Max. discharge current (8/20µs) (Imax): 40kA
Connections of a SPD to the loads should be as short as possible in order to reduce the value of the voltage protection level (installed Up) on the terminals of the protected equipment. The total length of SPD connections to the network and the earth terminal block should not exceed 50 cm. One of the […]
Background While small solar panels used for battery charging and similar tasks may not require special connectors, larger systems normally connect the panels together in series to form strings. In the past this was accomplished by opening a small electrical box on the back of the panel and connecting user-supplied wires to screw terminals within. […]
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 […]
