Acceptable Voltage Indicator Circuit
designed by David A. Johnson, P.E. |
|
|
| I have used this circuit many
times in custom test fixtures where a simple go-no go indication was needed. The
circuit can also be used to adjust a particular voltage be within specific high or low
limits. The three LEDs will indicate if the voltage is high, low or OK. When
connected to other converters, such as a frequency to voltage converter, a current to
voltage converter or a power to voltage meter, it could provide a quick indication of a
proper level. |
