Isolators
Isolators are essential components used to protect electronic systems by separating different parts of a circuit. They prevent unwanted current flow and eliminate noise interference, ensuring safe and reliable signal transmission.
These devices are widely used in industrial automation systems and power electronics where electrical isolation is critical for safety and performance.
Types of Isolators
We offer a variety of isolators designed for different applications:
Digital Isolators: Provide high-speed signal isolation for digital communication systems.
Optoisolators (Optocouplers): Use light to transfer signals between isolated circuits, ensuring complete electrical separation.
Optoisolators with Logic Output: Designed for digital interface applications with stable logic-level output.
Optoisolators with Triac/SCR Output: Suitable for AC load control and switching applications.
Gate Driver Isolators: Used in power electronics to safely drive high-voltage switching devices.
Applications of Isolators
Isolation components are widely used in various electronic and industrial applications:
