The RayDat SUI-4 Series<\/strong> provides the same electrical performance as the SLH-4 Series but features a 10 kA Iimp<\/strong> lightning impulse protection level per line and has higher surge resistance or impulse resistance. Raydat SUI<\/strong> is intended for operation in electrical environments where higher exposure to direct or partially direct lightning currents<\/strong> is experienced. These are wind turbines<\/strong> and PV plants where lightning exposure is more severe.<\/p>\n

Protection Technology | 10 kA Lightning Impulse Protection<\/strong><\/h2>\n

The initial protection stage consists of a three-pole gas discharge<\/strong> tube and is designed to divert the primary surge energy. The subsequent protection stage is realized using fast bidirectional silicon diodes. Thus, the diodes are prevented from burning out due to the incoming lightning impulse. The impulse first passes through these tubes and is slowed down. Special design techniques have been used in the design of the protection stage. With this special design, while products in other brands can provide maximum 5 kA protection, RayDat SUI-4 provides protection up to 10 kA lightning impulses.<\/strong><\/p>\n
