Notes
Output protection
Electronically protected against overload, no-load, and short-circuits. If there is a
protection event, audible noise may occur.
Output overvoltage
protection
30.5V DC typ, 32V DC max
If there is an internal power supply anomaly, a redundant
circuit limits the max output voltage. The output shuts down
and automatically attempts to restart.
Degree of protection
IP 20
EN/IEC 60529
Penetration protection
> 4 mm (0.16 in.)
For example, screws, and small parts
Over-temperature
protection
Yes
Output shuts down and the power supply automatically
restarts. The temperature sensor is installed on critical
components inside the unit and turns off the unit in safety
critical situations. Safety critical situations can include
when derating requirements are not observed, ambient
temperature is too high, ventilation is obstructed, or the
derating requirements for a mounting orientation are not
followed. There is no correlation between the operating
temperature and turn-off temperature since this is
dependent on input voltage, load, and installation methods.

Internal input fuse
Included
Slow-blow high-braking capacity fuse that is not user
replaceable.
