Ship navigation signal light circuit
Source: InternetPublisher:两手空空 Keywords: Signal lights transistors multivibrators Updated: 2020/12/24
A self- excited multivibrator is composed of transistors VTi and VT2 , and the output signal is amplified by VT3
and used as a trigger pulse for the thyristor. Adjusting the potentiometer RP can change the oscillation frequency of the oscillator, thereby adjusting the flash periods of Hi (red), Hz (green), and Ha (yellow) of each flash signal light .
