摘要

System of government of the level and of the duration of the supply tension in automation and control circuits. Checking the status of the voltage at a point (1) of the circuit is performed by an operational amplifier (8), on, as the tension is or not above a reference tension, a diode (d2) or another (d3) the reference voltage and the supply voltage are obtained from a voltage regulator (3) provided with noise filters (cl ... C5). Through elements that include push buttons (p1, p2, p3) and a relay (6), it is also given the control of the voltage in a particular point and during pre-setting times, which can be disabled some point in any instant.
