Abstract

"SISTEMA DETECTOR DE SUB-TENSãO EM UM APARELHO ELéTRICO". Tendo múltiplas cargas (10) associadas a chaves de acionamento (20) comandadas por respectivos controles eletrónicos (30) energizados por uma fonte de alimentação (40) conectada a uma rede elétrica e operativamente acoplados a um módulo de comando (50). O sistema compreende: uma carga compensadora (60) ligada à fonte de alimentação (40) e construída para manter constante a relação entre a tensão na rede elétrica e a tensão da fonte de alimentação (40), independentemente do número de cargas (10) sendo energizadas; uma unidade de controle (70) operativamente associada ao módulo de comando (50) e à carga compensadora (60), de modo a definir o consumo de corrente a ser produzido pela carga compensadora (60) e um meio sensor de tensão (S) operativamente associado à fonte de alimentação (40) e à unidade de controle (70) para conduzir à desenergização das cargas (10) quando a tensão da fonte de alimentação (40) for inferior a um valor mínimo predeterminado.
