Direct or alternating current supply control device for e.g. TV, has transformer with secondary coil delivering voltage for controlling relay through transistor, where relay is active when current passes in primary coil is sufficient

摘要

The device has a transformer (Ti) having a primary coil across which a current (i1) from a master output (SM) circulates. The transformer has a secondary coil delivering a voltage for controlling a relay (R1) through a transistor (T) after an adjustable delay generated by a timer. The relay is active when the current passes in the primary coil is sufficient. The relay closes and opens an electric supply circuit of a slave output (SE).
