LOW VOLTAGE POWER SUPPLY

摘要

The present invention relates to a low voltage power supply (1 ) equipped with discrete components. The power supply comprises a timer circuit (4) able to establish a time basis variable in the shooting of a main switch (5), switching the electric conduction of the supply (1). Moreover, the supply (1) also includes two other components capable of interfering with the switching frequency of the supply, namely: current limiter (13) and output voltage limiter (12). When the current limiter (13) detects an overcurrent situation or when the output voltage limiter (12) detects an overvoltage situation, a latch (14) is actuated causing the timer circuit voltage (4) to be deviated from the main switch (5) to itself, thus causing the opening of the main switch (5).
