Abstract

Indicating device for monitoring a range of voltages in a circuit, characterized in that it consists of two npn transistors that have their respective emitters connected directly to the negative terminal of the device, their collectors to the positive terminal by means of a resistor and a signaling means, respectively, and their respective bases each connected, on the one hand to the negative terminal by a resistor, and on the other hand, to the positive terminal via one in series with a zener diode, these two leds zener, have two load inputs, one for a voltage corresponding to the lower limit of the voltage zone, and the other, for a voltage corresponding to the upper limit of said area, the base of the transistor that is connected to the signaling means is connected to the junction between the collector of the other transistor and the resistor, by means of a conductor in which a connected diode is interposed. That allows the passage of current from the resistor to the base of the transistor connected to the signaling means. (Machine-translation by Google Translate, not legally binding)
