Abstract

CIRCUITO DE PROTECCION DE LA FUENTE LUMINOSA DE LOS TRANSMISORES OPTICOS. PARA UNA FUENTE LUMINOSA SE PREVE UN CIRCUITO DE PROTECCION QUE INCORPORA UN ELEMENTO TERMOSENSIBLE, FORMADO POR UNA FUENTE DE INTENSIDAD VARIABLE CON LA TEMPERATURA Y UN DIODO, DE TAL FORMA QUE SE ESTABLECE EN LA CORRIENTE TOTAL QUE CIRCULA POR LA FUENTE UN LIMITE MAXIMO VARIABLE QUE DEPENDE EN CADA MOMENTO DE LA TEMPERATURA A LA QUE ESTA TRABAJANDO LA FUENTE. UN ELEMENTO REGULABLE PERMITE UN AJUSTE DEL VALOR DE LA CORRIENTE DE PROTECCION PARA UNA TEMPERATURA INICIAL DE REFERENCIA, Y OTRO ELEMENTO REGULABLE PERMITE EL AJUSTE DE LA CONSTANTE DE PROPORCIONALIDAD CON LA QUE VARIA LA CORRIENTE DE PROTECCION CON RESPECTO A LA TEMPERATURA.
