Optocouplers - What’s that?
- Transfers analog/ digital signals between two isolated circuits by using light transmission
- Optoelectronic package with infrared LED & detector
- The optical transmission takes place with an infrared light beam
Why Optocouplers?
- Separation of low power control circuits from high power circuits (galvanic isolation)
- Optocouplers protect your application against overvoltages
- Safety Isolation: for circuits and persons from dangerous electrical installations
Performance
High CTR in low current operation
Stable CTR over whole temperature range
Reliability & Quality
Application Examples
Isolated Power Supplies
Providing robust galvanic isolation of feedback control loop in SMPS
Motor Driver / Control
Breaking ground loops and providing safety isolation in high-voltage motor drivers
AC or DC Voltage Detection
Safety isolation in phase-controlled AC motor, safety relays/switches, etc.
Industrial Control Systems
Ensuring noise immunity and safety in industrial environments
