for applications requiring high isolation voltages (20kV)
The optocoupler EL-HV50 is dedicated to applications requiring
high isolation voltages. The construction of the device results
in a creeping distance of 50mm. Even with a heavy soiling
( non-conductive dirt and temporary covering by dew) a rated
voltage of 5kV is permitted. This feature makes the EL-HV50
the right device for a variety of railroad applications.
The short delay time of typ. 250ns allows transmission if
fast digital signals. The receiver element is built from a
photodiode followed by a Schmitt-trigger device that generates
a logic signal at its open collector output.
