Optocouplers for AC/DC Power Supplies

Isolation is critical to protect both an electronics system and the user from potentially hazardous voltages, or where a high level of electrical isolation between electronics systems is necessary. Digital isolators are known for their speed of data transmission, high level of magnetic immunity, and long life expectancy.
