Blitz
DC SPD 1000V
The Blitz DC SPD 1000V is a high-performance surge protection device designed for advanced DC systems such as large-scale solar PV installations, battery energy storage systems (BESS), and industrial DC panels. It effectively protects equipment from dangerous overvoltage surges caused by lightning and switching transients. This Type 2 SPD features a fast-acting mechanism, compact DIN-rail mounting, and reliable visual status indication.
