The Citel DS50PVS-1000G/51 SPD (Surge Protective Device) is a specialized type 2 surge protector tailored for photovoltaic (PV) power supply networks, designed to safeguard against lightning surge voltages. This device is specifically engineered to protect PV installations where the risk of electrical surges, typically induced by lightning strikes, can cause damage to sensitive equipment. Type 2 Surge Protection: Designed to handle surge events commonly encountered in PV systems, including lightning strikes and other transient voltage surges. Voltage Rating: Rated for up to 1000VDC, suitable for PV systems operating at high voltages. High Surge Current Capacity: Capable of managing surge currents up to 15kA (kiloamperes), ensuring robust protection against high-energy surges. Varistor-Based Protection: Utilises specific varistors optimised for PV applications, providing effective protection in both common mode (between PV lines and ground) and differential mode (between PV lines). Reliable Performance: Engineered for durability and reliability under extreme weather conditions and over its operational lifespan. Compact Design: Compact form factor suitable for integration into PV array combiner boxes or other installation points within the PV system. Easy Installation: Designed for straightforward installation by qualified technicians, facilitating quick deployment and setup in PV installations.
