Note
These AC/DC power supplies are not convection rated therefore stock numbers 192-1201, 192-1223, 192-1239 and 192-1267 which are not supplied with a fan require the user to provide 30CFM forced air cooling through the length of the power supply.
Derating from 50 to 70°C is 2.5% per °C.
Suitable connecting kit for this AC/DC power supply: stock number 151-717
