Abstract
A device for powering one or more electric/electronic devices operatively associated with a low-voltage circuit breaker takes energy from a power supply line. An electronic regulator receives the energy collected as an input and delivering as an output to the electric/electronic device a power supply voltage (Vout) having a value within a preset range with respect to a reference voltage (VR). The electronic regulator includes an energy storage device chargeable by the energy collected, at the terminals of which a voltage (VCL) is established that is indicative of the power supply voltage (Vout) delivered to the electric/electronic device. A circuit enables/disables the charging of the storage device, and a feedback circuit receives a signal indicative of the voltage (VCL) at the terminals of the storage device and sends a signal to the enabling/disabling circuit to trigger the disabling or enabling of the charging process in order to keep the value of the voltage at the terminals of the storage device within a preset range. The feedback circuit enables the charging phases so as to power the storage device continuously up until the value of the voltage at their terminals comes within the preset range.
