Surge Arrestor DC-3GHz SEMPER

Surge Arrestor DC-3GHz, 230V static SOV, SEMPER

Description

These SurgeShield Connectors (SSC) are gas discharge tube (GDT) surge protective devices designed to protect information and communication systems from surge voltage caused by lightning. The SSC are supplied together with an inserted GDT of 230 V static spark-over voltage. The IP68 rating makes it useable for any outdoor application.

  • DC cut-off frequency (3 dB) up to 3 GHz
  • Excellent RF performance
  • 140 W CW power rating
  • Maximum discharge current 20 kA
  • O-ring sealed to panel
  • Easy to install

SEMPER Technology

The SEMPER concept enhances the safety and reliability of the well known and proven gas capsule protector principle impressively. It eliminates the risk of capsule “hold on” due to DC line powering or high powered RF signals, which will render the system inoperable and can destroy the protective capsule.

Features and benefits

  • self extinguishing gas capsule with automatic recovery
  • extinguishes under any coaxial line condition including:
    – malfunction of electronic fused DC supplies
    – malfunction of RF line monitoring
    – absence of any such mechanism
  • can be employed for any HUBER+SUHNER gas capsule protectors with exchangeable gas tube
  • field replacement allows cost-effective system upgrades
  • product options ensure availability for any application
  • higher safety
  • negligible system downtime
