The VPD1500 series are Type 1+Type 2 surge protection devices for DC systems up to 1500V, delivering 6.25kA impulse current and 40kA maximum discharge capacity, ideal for photovoltaic and other high-voltage DC protection applications.
The VPM1000-50/3N+NPG(T1+T2), AC255V/1000V SPD is combined Type 1+Type 2 surge protective devices (SPDs) featuring an integrated design that provides coordinated two-stage protection within a single unit. It enables high-energy impulse current (Iimp) discharge for primary protection at the LPZ0–1 boundary, followed by fine protection with low residual voltage. This makes the series an ideal, space-saving solution for main power inlets and distribution boards in commercial, industrial, and critical infrastructure applications requiring maximum reliability against lightning and surge threats.
VPD1000-40/3P (T1+T2), DC1300V SPD demonstrates high safety, reliability, and exceptional grid compatibility. It is ideally suited for renewable energy applications including photovoltaic and energy storage systems. Designed for installation in DC power distribution systems, converters, inverters, and combiner boxes within LPZ0 to LPZ1 zones, it provides reliable protection for sensitive electrical equipment against damage caused by direct lightning strikes or induced transient overvoltages.
Digital twin, Internet of Things, big data, artificial intelligence, industrial Internet and other technologies are applied to realize digital design, intelligent production, intelligent management, collaborative manufacturing, green low-carbon manufacturing, and security management.
