Product description format_size zoom_out zoom_in

  This constructor will allow a radio amateur to assemble a simple LED voltage level indicator. A four-LED indicator will allow you to easily control the state of the car's on-board network, or the voltage level on a 12V lead battery.

Specifications:

  • Input voltage: 10 - 30V
  • Current consumption: 25mA

Device Description

  The device is assembled on a single U1 chip, which is four operational amplifiers. Each amplifier is included as a voltage comparator. When the switching voltage of the comparators is exceeded, LEDs D1-D4 are lit in series. Table 1 shows the correspondence between the glow of the LEDs and the voltage on the battery. Adjusting R5 should adjust the glow of all LEDs at a voltage of 14.4V.
