Preguntas frecuentes
SAI significa Sistema de Alimentación Ininterrumpida y es un dispositivo que proporciona un suministro continuo de energía para proteger las cargas críticas de los cortes o fluctuaciones de energía.
La función principal de un SAI es proporcionar una fuente de alimentación de reserva para garantizar que los equipos críticos puedan seguir funcionando cuando la red eléctrica se interrumpe o es inestable, evitando la pérdida de datos o daños en los equipos.
El SAI se divide principalmente en tres tipos: offline, online y online interactivo.
A la hora de elegir la capacidad de potencia del SAI, hay que tener en cuenta la demanda total de potencia de la carga, normalmente se recomienda elegir una potencia ligeramente superior a la carga total del SAI para garantizar un tiempo de espera suficiente.
El tiempo de espera de un SAI depende de la capacidad de la batería y de la potencia de la carga. El tiempo de espera suele oscilar entre 10 minutos y varias horas, y las necesidades específicas pueden determinarse en función del escenario de aplicación real.
