Optoisolators are electrical current protecting devices. They work by using optical isolation to separate a receiving device from a source of current. The EL3082 Triac, SCR Output is a type of optoisolator that uses a triac or Thyristor as the output device. It can be used in a number of applications including AC and DC power switching, motor speed control, dimming control, and temperature measurement.

The EL3082 consists of an LED and a triac or thyristor, both of which are isolated from each other with a high-quality photo coupler device. The criteria for selection is dependent upon the application and determines the characteristics of the LED, photodiode, and field effect transistor (FET). The LED is typically operated in an inhibited state. When the LED is illuminated, its output is absorbed by the photosensitive component. An electric signal is then generated to drive the output FET. This allows the output triac or thyristor to be turned on or off, depending on the input signal.

The EL3082 is most typically used for switching AC or DC power. Its two most common applications are motor speed control and dimming control. In a motor speed control application, the EL3082 is used to regulate the amount of current supplied to the motor. This is accomplished by sending a voltage signal to the LED, which then causes the output triac or thyristor to turn on, thereby controlling the amount of current supplied to the motor and its speed. In a dimming control application, the EL3082 is used to regulate the amount of light output from a light source. The EL3082 is also used in temperature measurement systems where its input is dependent upon a temperature sensor or thermostat.

The EL3082 is a reliable optoisolator device and is suitable for a variety of applications. It can be used to provide efficient power switching, motor speed control, dimming control, and temperature measurement. The device can operate with either an AC or DC signal and has excellent noise immunity, making it a sound choice for applications with high levels of electromagnetic interference.
