As the number of direct current (DC) applications continues to grow, more and more facility operators are also using 650 to 750 V DC in industrial settings. In addition to electromobility, DC is also used for battery storage. If the energy supplied by wind or solar power plants has to be converted first, valuable energy is lost.
DC applications also require reliable protection against overvoltages caused by lightning strikes or switching operations. Surge protection devices specifically developed for these applications provide reliable protection against high voltages. Depending on the system voltage, the two variants, VAL-MB-T2-750DC and VAL-MB-T2-1000DC, offer the appropriate solution for different application areas. They can be used at altitudes up to 6000 m above sea level. A mechanical-optical status indicator provides information on the status of the protection module. Thanks to the integrated remote signal, they can also be integrated into the control room. Their compact, space-saving design makes them ideal for installations in confined spaces.
