17. PROTECTION FEATURES
Output protection Electronically protected against overload, no-load and short-circuits
*)
Output over-voltage protection Typ. 30.5Vdc
Max. 32Vdc
In case of an internal DC/DC converter defect, a
redundant circuit limits the maximum output voltage.
The output shuts down and automatically attempts to
restart.
Degree of protection IP 20 EN/IEC 60529
Penetration protection > 4mm E.g. screws, small parts
Over-temperature protection
**)
Yes Output shut-down with automatic restart, no signalling
Input transient protection MOV (Metal Oxide Varistor)
Internal input fuse DC suitable fuse included Not user replaceable
Reverse input polarity protection Yes Unit does not start, no signalling
*) In case of a protection event, audible noise may occur.
**) The temperature sensor is installed close to critical components inside the unit and turns the unit off in safety critical situations (e.g.
customer does not care about de-rating requirements, ambient temperature too high, obstructs the airflow or install the unit in
unsuitable mounting orientation)
There is no correlation between the operating temperature and turn-off temperature since this is dependent on input voltage, load and
installation methods.
18. SAFETY FEATURES
Classification of output voltage SELV IEC/EN 60950-1
PELV IEC/EN 60204-1
Double or reinforced isolation to the input voltage
Class of protection I PE (Protective Earth) connection required
Isolation resistance
> 500MOhm At delivered condition between input and output,
measured with 500Vdc
> 500MOhm At delivered condition between input and PE,
measured with 500Vdc
> 500MOhm At delivered condition between output and PE,
measured with 500Vdc
> 500MOhm At delivered condition between output and DC-OK
contacts, measured with 500Vdc
PE resistance < 0.1Ohm
Resistance between PE terminal and the housing in the
area of the DIN-rail mounting bracket.
Touch current (leakage current) The leakage current which is produced by the DC/DC converter itself depends on the
input voltage ripple and need to be investigated in the final application.
For a smooth DC input voltage, the produced leakage current is less than 100μA.

All parameters are typical values specified at 24V, 8.3A output, 110Vdc input, 25°C ambient and after a 5 minutes run-in time
unless otherwise noted.
