- PSU will turn OFF when the output is currently ON and the connection of these control pins lasts for more than 3 seconds.
- The PSU will turn ON when the output is currently OFF and the connection of these control pins lasts for more than 100 ms seconds.
- To eliminate unwanted output toggling (if an external button is pushed too long) the PSU ignores additional change requests until the pins have been disconnected for 1 second. (a continuous SHORT/OPEN version can be implemented – consult factory). Temperature Warning (Connector J3, Pins #3 and #5) These pins are used to indicate when the unit is within 20 °C of the maximum temperature prior to execution of automatic thermal shutdown. This signal can be used by an external monitoring system to indicate when the unit is operating fairly close to the thermal shut down temperature.
- This interface is isolated from any internal electronic connection or grounds.
- These pins are shorted together (CLOSED condition) when the baseplate temperature is within 20°C of the thermal shutdown threshold. The connection's resistance is 50 Ω or less, measured across these pins. The connection is capable of handling at least 40 mA from an external source in this condition
- These pins are disconnected (OPEN condition) when the baseplate temperature is below 20 °C of the thermal shutdown threshold. The connection resistance is higher than 100 kΩ measured across these pins. Thermal Shutdown Warning (Connector J3, Pins #4 and #5) These pins are used to indicate when the unit is within 10 °C of the maximum temperature prior to execution of automatic thermal shutdown.
