The isolator can also be used in medical devices and measurement equipment. Other application fields include aerospace applications, hybrid electric vehicles, military systems, and instrumentation.

Working Principle

The PS9308L2–V-E3-AX isolator utilizes an opto-coupler to transmit optical signals between the two sides of the transformer. The opto-coupler consists of an LED and a photodiode, with the LED emitting light when a voltage is applied to it, and the photodiode converting the light to electric current. When the LED is illuminated, it causes a current to flow through the photodiode, which can be used to drive a gate on the secondary side of the transformer. This open-collector circuit enables the isolator to quickly connect and disconnect loads that are connected to the secondary side of the transformer.

Conclusion

The PS9308L2-V-E3-AX is an isolator designed specifically for System 9 (S9) applications. It integrates isolation and protection into a single package, reduces electromagnetic interference, and provides up to four optically isolated channels. Additionally, it is capable of high-speed switching and wide voltage range, making it ideal for use in power systems, machine drive systems, data processors, and industrial automation.
