Abstract

LA INVENCION SE REFIERE A UN SISTEMA ELECTRONICO QUE INCLUYE UNA ALIMENTACION ELECTRICA QUE SUMINISTRA UN VOLTAJE DE TRABAJO Y UN CIRCUITO DE REARME. EL CIRCUITO DE REARME INCLUYE UN CIRCUITO DETECTOR DE VOLTAJE, ACOPLADO A LA ALIMENTACION ELECTRICA, PARA GENERAR UNA SEÑAL DE CONTROL CUANDO EL VOLTAJE DE TRABAJO CAE POR DEBAJO DE UN VALOR PREDETERMINADO. UN CIRCUITO DE CONTROL GENERA UNA SEÑAL DE REARME EN RESPUESTA A LA SEÑAL DE CONTROL. UNA CIRCUITERIA ADICIONAL SUMINISTRA POTENCIA AL CIRCUITO DE CONTROL, INDEPENDIENTEMENTE DE LA ALIMENTACION ELECTRICA, CUANDO EL VOLTAJE DE TRABAJO CAE POR DEBAJO DEL VALOR PREDETERMINADO.
