Este elemental circuito, es útil en bancos de trabajo donde se reparan equipos electrodomésticos<br /> <br /> == Introducción ==<br /> <br /> Se trata de una modificación al diseño de los [[reguladores de voltaje]] que censa el [[voltaje]] de alimentación y lo compara con uno prefijado o tope.<br /> <br /> Cuando resulta superior, lo desconecta de modo automático y solo se restablece al alcanzar su valor normal. Protege hasta 13,5 V<br /> <br /> == Circuito ==<br /> <br /> En el circuito, el [[Zener]] de 12v y un BC557 censan la entrada según sea el voltaje. El [[diodo]] D2 se polariza directa o inversamente y lleva el K1814 al punto de saturación o corte, lo que le permite el paso de la alimentación al equipo a través del [[relay]].<br /> <br /> Su eficiencia ha sido probada en reproductores, radios y [[fuentes de alimentación]] de voltaje fijo, con peligro de sobrevoltaje<br /> <br /> == Componentes ==<br /> • BC557<br /> • KT814<br /> • R1 (10K)<br /> • R2 (1K)<br /> • R3 (680)<br /> • R4 (2,2K)<br /> • Relay 12 V.<br /> • D1, D2, D3 (Diodos de silicio) <br /> <br /> == Fuentes ==<br /> <br /> *Revista Juventud Técnica No 319<br /> <br /> [[Category:Electrónica]]</div>
