Protector de Motores Trifásicos (CIR1275S)

Written by: Newton C. Braga
Category: Banco de circuitos

 

El circuito mostrado en la figura salió en un artículo de una revista Modern Electronics de 1990. La revista ya no existe, pero el circuito es actual, pudiendo ser montado con facilidad. Los transistores pueden ser cambiados por los BC558. Lo que el circuito hace es accionar un relé de alarma o apagar el motor si una de las fases de su alimentación faltar. Los transformadores tienen un secundario de 24 V con corriente de 200 a 500 mA. Los demás componentes no son críticos.
