Optoisolators, also known as optocouplers, are semiconductor-based components used to prevent unbalanced line voltages from upsetting the AVC circuit or other sensitive electronics. They act as an electrical insulation barrier between two circuits. There are several types of optoisolators such as triac, SCR output (EL3082-V). This article aims to discuss their application field and working principle.

EL3082-V optoisolators are designed for controlling AC or DC circuits. They are mainly used in lighting and audio-visual systems, lamp ballast dimmers, reversible motors, industrial control panels and safety equipment. They are also used in home automation and industrial power supplies.

EL3082-V optoisolators are based on a photo-SCR output. The SCR output is triggered by the LED when a current is applied to the input of the optoisolator. When the SCR output is triggered, the voltage on the output side will rise until the current on the primary (input) side reaches the threshold. The SCR output will then turn off. The optoisolator will stay off until the current on the input side drops below the threshold.

The EL3082-V optoisolator allows for a large operating voltage range (0-280V). This enables it to be used with a wide variety of applications from 0 to 400V, both AC and DC. The EL3082-V also has a high power dissipation capability of up to 0.75 W. This makes it suitable for applications that require high current control. Furthermore, the optoisolator has an input drive current range of 0.3 mA to 10 mA. This feature allows for a precision control of the output by varying the input drive current.

The EL3082-V optoisolator also features a built-in protection circuit that protects the LED from high voltage surge. This feature is useful for applications that require fast switching. Furthermore, the optoisolator is also equipped with an over-current protection circuit that prevents excessive current from flowing in the output.

In summary, EL3082-V optoisolators are useful for controlling AC or DC circuits. They are mainly used in lighting, audio-visual systems, lamp ballast dimmers, reversible motors, industrial control panels and safety equipment. Furthermore, the optoisolator has a wide operating voltage range, high power dissipation capability and an input drive current range of 0.3 mA to 10 mA. It also has a built-in protection circuit that protects the LED from high voltage surge and an over-current protection circuit that prevents excessive current from flowing in the output. The EL3082-V optoisolator is thus an ideal solution for controlling AC or DC circuits in various applications.
