Title (EN) SWITCHED DUMMY LOAD FOR MONITORED AC LOADS
(FR) CHARGE FACTICE COMMUTEE POUR DES CHARGES CA SURVEILLEES
Abstract: front page image
(EN)Disclosed is electrical control apparatus (500) comprising a first switch (508) configured to couple an electrical supply (502) to a primary electrical load (512) according to a value of a control signal (510). A second switch (554) is configured to couple the primary load (512) to a dummy electrical load (556) according to an inverse value (552) of the control signal (510). The apparatus includes means (550) for applying the control signal to the first switch and an inverse thereof simultaneously to the second switch. The switched dummy load (556) finds particular application ameliorating the effect of false “on” indications in traffic lamp controller circuits (600).
(FR)L'invention concerne un appareil de commande électrique (500) comprenant un premier commutateur (508) conçu pour relier une alimentation électrique (502) à une charge électrique primaire (512) selon une valeur d'un signal de commande (510). Un second commutateur (554) est conçu pour relier la charge primaire (512) à une charge électrique factice (556) selon une valeur inverse (552) du signal de commande (510). L'appareil comprend un moyen (550) pour appliquer le signal de commande au premier commutateur et l'inverse de celui-ci, simultanément, au second commutateur. La charge factice commutée (556) est particulièrement appropriée à des applications destinées à améliorer l'effet d'indications de 'marche' factices dans des circuit de contrôleur de feu de circulation (600).
