A frequent cause of electrical/electronic equipment failure is AC power line surges. This is especially true in the case of sensitive electronic equipment such as CATV systems, traffic controllers, data processing equipment, telecommunications systems, etc. These power line surges can vary from noise-like transients to spectacular lightning induced surges. Therefore, the effect on costly equipment can vary from a slow degradation of performance to catastrophic failure. The SPD130K solid state arrester has been designed to effectively dissipate high energy surges up to 130KA (8 x 20us). High energy induced surges usually originate on the primary side of the power transformer and consequently are transferred to the secondary.
The SPD130K design incorporates patented, UL approved, high energy, thermally fused MOVs in series with an inductive network. The inductive network is followed-up by a powerful high current transient suppressor. This configuration offers a low clamp voltage of 296 volts on a 20KA surge. The powerful SPD130K also offers separate LED status indication for each of the three modes of protection.
