RS422 isolator, 50 kV

  • RS422 isolator 50kV

Lightning protection for copper wiring


General information:

  • Galvanically isolated connection between two RS422 devices
  • 50kV isolation
  • integrated into the cable
  • No re-configuration of transmission parameters required
  • No separate power supply necessary
  • Ideal solution for the connection of medical equipment or high-voltage measuring devices to a PC
  • Effective lightning protection as a connecting cable

Background information:

There is no protection against damage from lightning that hits your wiring system directly, due to the extremely high energy of the bolts. However, it is useful to protect your IT installation against damage from lightning that impacts on lines far away from your premises by using electrical isolators. An isolation of only 1kV already reliably prevents any lightning damage. With an electrical strength of 50kV, the chance for such damage is practically nil. The experience of the last few years shows that customers, who had considerable damage done to their IT devices by lightning, reported no such incidents since they had installed isolators.
