Optoisolators, also known as optocouplers, are electrical components that allow for transmission of electrical signals between two tightly coupled parts while maintaining electrical isolation between the two parts. The CNY17-3-360E is a current sensing photovoltaic optoisolator transistor that is used to separate the input and output circuits in order to decrease the risk of high voltage or current disturbances or disturbances from being transmitted to sensitive systems or components.

The CNY17-3-360E optoisolator relies on two main components for operation: a light-emitting diode (LED) and a phototransistor. The LED transmits the electrical signal across the isolator’s air gap using light pulses. The phototransistor recei ves these light pulses and amplifies them. The current sensing photovoltaic optoisolator is used to measure or sense the magnitude of current flowing through a circuit, and can also be used to adjust lighting, heat, and other applications where current control is needed.

The working principle of the CNY17-3-360E optoisolator is fairly straightforward. The circuit begins with an input of the current sensing photovoltaic optoisolator, typically pulsed at a frequency of 1000 Hz or higher. The LED in the optoisolator will produce light pulses at the same frequency, which will then be received by the phototransistor and amplified. The amplified signal is then fed back to the input circuit to further control the level of current being applied. This amplification of the input allows the precise control of the current flowing through the circuit.

The CNY17-3-360E optoisolator can find uses within a wide range of applications such as measuring, adjusting, and controlling current in lights, motors, pumps, and other electro-mechanical devices. Its ability to provide isolation between the input and output circuits ensure reference accuracy, precise control, and protection of the input circuits from disturbances. Its high frequency response and low power consumption make it ideal for these applications.

The current sensing optoisolator circuit only requires low voltage and offers robust design. It is approved to IEC 61000-4-2, which is the international standard for electromagnetic compatibility (EMC). The CNY17-3-360E operates from -30 to +75 °C and is housed in an epoxy-coated, four-pin molded plastic package. Its compact size allows for easy integration into any circuitry.

In summary, the CNY17-3-360E current sensing photovoltaic optoisolator is a versatile and reliable electrical device that is widely used in a variety of applications. It provides isolation between circuits, high frequency response, robust design, low power consumption, and precise control. Its ability to meet the international standard for EMC approval also makes it ideal for applications requiring reliable signal transmission under a wide variety of conditions.
