Dispositivos de protección contra sobretensiones para tecnología de redes y salas de servidores
Los dispositivos de protección contra sobretensiones en la industria electrónica son componentes especializados diseñados para proteger los aparatos de las sobretensiones repentinas causadas por rayos o transitorios en la red eléctrica. Suelen consistir en elementos de protección como varistores, descargadores de gas o atenuadores de tensión transitoria, que disipan el exceso de tensión y evitan así que dañe los componentes electrónicos sensibles. En aplicaciones industriales, los dispositivos de protección contra sobretensiones suelen utilizarse en sistemas de control de máquinas, redes de datos y sistemas de comunicación. Funcionan reduciendo la tensión a un nivel seguro en caso de sobretensión, prolongando así la vida útil de los dispositivos conectados y garantizando su funcionamiento.
¿Tiene alguna pregunta sobre nuestra gama de dispositivos de protección contra sobretensiones?
Dispositivos de protección contra sobretensiones para sistemas de control eléctrico
Los dispositivos de protección contra sobretensiones se utilizan en numerosos ámbitos en los que es necesario proteger dispositivos electrónicos sensibles de los peligros de los rayos o las sobretensiones eléctricas. En la industria, estos dispositivos se utilizan a menudo para proteger las máquinas de producción y los sistemas de control. Los dispositivos de protección contra sobretensiones son especialmente indispensables en los procesos de fabricación automatizados, ya que protegen contra los picos repentinos de corriente que pueden provocar los rayos o las operaciones de conmutación en la red eléctrica.
Los dispositivos de protección contra sobretensiones también son esenciales en la industria informática y de telecomunicaciones para proteger de daños las salas de servidores y las tecnologías de red. Los dispositivos de Okaya y Bourns, que ofrecen una protección fiable contra transitorios, se utilizan principalmente en este sector. Los dispositivos de protección contra sobretensiones también se encuentran en los hogares modernos, donde protegen de las sobretensiones a dispositivos sensibles como ordenadores, televisores y electrodomésticos. Estas soluciones no sólo evitan averías en los dispositivos, sino que también ayudan a prolongar la vida útil de los aparatos electrónicos.
