Specifications:
The document outlines the specifications for a DC surge protective device used in photovoltaic systems. It includes details on remote control contact, signal access range, and recommended wire specifications for both AC and DC systems. For AC, the maximum voltage is 250V with a current of 0.5A, using single-core wire up to 1.5mm. For DC, the maximum voltage is 60V with a current of 0.1A, using multi-core wire up to 1.3mm.
Model Information:
Models include FV20C/2+NPE-500PV(S), 600PV(S), 800PV(S), and 1000PV(S). If the model number lacks an 'S', it does not have a remote control contact function.
