RJ11 Signal Surge Protector LP-C/RJ11/L

Model LP-C/RJ11/L

LP-C/RJ11/L signal surge protector in an aluminium shell with standard RJ11 connectors, protecting telephone, fax and control system lines from lightning-induced overvoltage, with 2.5 kA discharge current and 40 MHz transmission rate.

Overview

About the RJ11 Signal Surge Protector LP-C/RJ11/L.

The LP-C/RJ11/L is an RJ11 signal surge protector in an aluminium profile shell, used on telephone, fax and control system lines. It prevents damage to connected systems and equipment from induced overvoltage and other instantaneous surge voltages generated by lightning or industrial noise. A multi-level fine protection circuit with high-speed surge protection components reacts quickly, with a line-to-line response time of 1 ns or less, while keeping a low output residual voltage and good transmission performance. Standard RJ11 signal connectors make it simple to insert into an existing line.

Features

  • Aluminium profile shell: durable, with a good shielding effect
  • Standard RJ11 signal connectors for easy use and a reliable connection
  • Multi-level fine protection circuit using high-speed surge protection devices
  • Fast response: 1 ns or less line to line, 100 ns or less line to ground
  • Low output residual voltage and transmission rate up to 40 MHz
  • Insertion loss of 0.5 dB or less
  • Nominal discharge current 2.5 kA (8/20 µs)
  • Protects lines 3 and 4

Applications

  • Telephone and fax lines
  • Program-controlled computer rooms
  • Control systems
