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
Impulse current Iimp 1. Where there are no national regulations or specific regulations for the type of building to be protected: the impulse current Iimp shall be at least 12.5 kA (10/350 µs wave) per branch in accordance with IEC 60364-5-534. 2. Where regulations exist: standard IEC 62305-2 defines 4 levels: I, II, III and […]
DC SPD applied to the Din rail type protects the DC electric system from surge. Also, the system allows replacement of the protective element (MOV), ensuring convenience and reduced cost. However, as only the protective module is provided, other components should be added when the system is installed in accordance with the site condition.
