This earthing bar with 7-fold overvoltage protection DLBS 3001 from Dur-line protects your devices from voltage peaks, which usually occur during a thunderstorm, right at the input. Short, pulse-shaped voltage peaks, which usually occur during a thunderstorm, are filtered out with this overvoltage protection. Secure your electronic devices with the DUR-line® DLBS 3001. Only a fantastic 0.3 dB transmission loss. Due to global warming, we have a proven increase in severe storms every year. In connection with this, more and more lightning strikes are occurring in Germany. This creates impulse-like electric fields which can still have a destructive effect at a distance of several 100m. The resulting overvoltages destroy the electrical devices connected via the antenna, such as multi-switches, LNBs, receivers and TV sets. These electromagnetic fields, which generate induction peaks here, reach the electrical devices unhindered via the coaxial cable. The Dur-line® DLBS 3001 protects your devices here for little money.
This overvoltage protection should be screwed directly to each input of the multiswitch or directly to each LNB output. The insertion loss of this DLBS 3001 is only 0.3dB.
Technical specifications: Connections: F-connector - F-socket Suitable for outdoor use; F connector with sealing ring DC pass-through for remote power supply Frequency range: 5 to 2500MHz Impedance 75 ohms Transmission loss: 0.3dB Solid metal body Shielding factor 100 dB Digital ready Return loss greater than 20dB Ampacity 8 KA (8/20 üs) Dimensions: length 4 cm, diameter 1.4 cm
Inside the Dur-line® DLBS 3001, a gas conductor acts as a voltage monitor. If the voltage between the core and the shield exceeds 200 volts, a short circuit occurs in this gas path and short-circuits surge currents of up to 8,000 amperes before they can have a destructive effect on the devices downstream.
When the overvoltage is over, the gas conductor switches back to protection.
Ground Bar: The grounding bar is used for potential equalization and lightning protection of the system.
Important instructions: Easy installation, as cables can be screwed on directly using F-connectors.
