Abstract (en)

Electronic thermoregulator (1) comprising first output terminals (7) connected to electrical/electronic loads/devices (5), a second output terminal (8) connected to an LED lighting device (6), a first circuit branch (9) having a first power supply voltage (VI), an SMPS switched-mode power supply (10) which is designed to supply a second voltage (V2) corresponding to a low direct voltage less than the first voltage (VI), a second circuit branch (11) which is electrically connected to the output terminal of the SMPS switched-mode power supply (10), of the relays (12) to connect the first circuit branch (9) to a first output terminal (7), an electronic switch (13) configured to switch on the basis of a relative second command signal (Sl) in order to connect the second circuit branch (11) to the second output terminal (8), and a control module (14) which generates the first command signals (Ki) and the second command signal (Sl) to switch the relays (12) and the electronic switch (13).
