Optoisolators, also known as optocouplers or optical isolators, are electronic components that transmit data signals between two locations while preventing the circuits on either side from electrically interfering with each other. The PS8802-2-F3-AX optoisolator is a type of optoisolator that utilizes a photovoltaic output transistor to provide isolation between input and output circuits. It is commonly used in a variety of applications to protect sensitive circuits from voltage surges, electro-magnetic interference (EMI) and other electrical disturbances. The following sections provide an overview of the application fields and working principles of the PS8802-2-F3-AX optoisolator.

Applications

The PS8802-2-F3-AX optoisolator is a popular choice for applications where the input and output circuits must be electrically isolated from each other, such as in industrial control systems, audio systems, and medical equipment. The optoisolator is a preferred choice due to its high level of isolation and its ability to handle very high input voltages up to 300 VAC. It is also commonly used in motor-control applications where it works as a switch to control the speed and direction of motors. The PS8802-2-F3-AX optoisolator can also be used to protect analog or digital input Signals from electrical noise or other disturbances.

Working Principles

The PS8802-2-F3-AX optoisolator is a Transistor, Photovoltaic Output (TPO) optoisolator. It contains a combination of an LED and a photosensitive static coupling device that operate together. When power is applied to the LED, it emits light which is then detected by the photodiode. The photons in the light cause an electrical current to flow through the photodiode which is then amplified by the output transistor. This amplified signal is then sent to the output circuit, effectively isolating the input and output circuits.

The PS8802-2-F3-AX optoisolator eliminates potential ground loops and common mode noise between the input and output circuits. This type of optoisolator can operate reliably in temperatures up to 105°C and can also handle high capacitive loads of up to 10 nF. It is also designed to withstand high voltage transients of up to 8 keV, making it well-suited for applications where high levels of electrical isolation are needed.

Advantages

The PS8802-2-F3-AX optoisolator offers several advantages that make it a popular choice. It is easy to install and requires minimal wiring, and is compatible with both AC and DC applications. It is also highly reliable and offers up to 3000VAC or 4250VDC of electrical isolation, which makes it well-suited for protecting circuits against voltage surges and EMI. The optoisolator is also a cost-effective solution, making it attractive for a variety of applications.

Conclusion

The PS8802-2-F3-AX optoisolator is an effective way to provide electrical isolation between input and output circuits while protecting against voltage surges and other potential hazards. It is easy to install, highly reliable, and compatible with both AC and DC applications. Additionally, it is cost-effective, making it a popular choice for industrial control systems, motor-control applications, audio systems, and medical equipment.
