Thermal shutdown/restart
(1)
(1) The OSSD outputs are semi-conductor PNP transistors and are safeguarded against over-temperature at the semi-conductor
junction. They are rated at 0.2A and don’t exceed the trip temperature unless the current significantly exceeds this rated value.
This protection does not trip out the complete switch when it is exposed to ambient temperatures greater than 55 °C (131 °F). It
would only switch off the OSSDs and the LED indicators would flash red to indicate a non-recoverable fault.
