DT-TELE-SHDSL Protector de sobretensión
Protector de sobretensión DSL Modem
- Protección para interfaces de telecomunicaciones SHDSL
- Adaptador de protección para dos pares de señales mediante conector RJ45 (RJ12) o conector atornillado
- Carcasa metálica resistente
- Dos puertos SHDSL
El protector de sobretensión DT-TELE-SHDSL ha sido diseñado para cumplir los requisitos especiales de transmisión de datos SHDSL. Ha sido especialmente diseñado para proporcionar protección contra rayos, interferencias de radiofrecuencia, descargas electrostáticas y sobretensiones transitorias para la máxima seguridad de los datos con una mínima atenuación de la señal.
Protección contra sobretensiones para sistemas SHDSL
Las telecomunicaciones fiables son imprescindibles en la industria de hoy. Los sistemas sensibles utilizados en estos casos funcionan con altas frecuencias en niveles de baja señal y están conectados en red sobre un área amplia. Las subidas de tensión conducen rápidamente a errores importantes y, en el peor de los casos, la pérdida de datos. El protector de sobretensión SHDSL adopta la forma de un adaptador que se puede instalar fácilmente entre cables de telecomunicaciones de entrada y un módem. La conexión por enchufe garantiza una instalación rápida y flexible y sólo necesita estar conectado a tierra mediante el cable negro o base de carril DIN.
Conector macho con protección contra sobretensiones para dos interfaces de telecomunicaciones SHDSL (puertos). Conexión: RJ45 (RJ11/RJ12) y bloque de terminales de tornillo conectables (COMBICON). Como alternativa, se puede fijar a un carril DIN.

Protection Against Surge Voltage |
Digital telecommunications systems (DSL) are safely protected against surge voltage by SHDSL Surge Protectors. Due to the high bandwidth of the surge protectors, the transmission signal is not influenced. Use is possible up to DSL 16000. All signal wires and the ground conductor must be connected to the surge protector according to the connection scheme. Any DIN rail should be grounded. |
