Opticalcoupler equipment advantages

The main advantages of the opticalcoupler equipment are: one-way transmission of the signal, the input end and the output end are completely electrically isolated, the output signal has no influence on the input end, the anti-interference ability is strong, the work is stable, no contact, long service life, transmission efficiency high. Opticalcoupler equipments were developed in the 1970s and are widely used in electrical insulation, level shifting, interstage coupling, drive circuits, switching circuits, choppers, multivibrators, signal isolation, interstage isolation, Pulse amplifier circuit, digital instrumentation, long-distance signal transmission, pulse amplification, solid state relay (SSR), instrumentation, communication equipment and computer interface. In the monolithic switching power supply, the opticalcoupler equipment feedback circuit can be constructed by using the linear opticalcoupler equipment, and the duty ratio can be changed by adjusting the current of the control terminal to achieve the purpose of precision voltage regulation and realize signal reception and transfer.
