QTD20.241
Q-Series
24V, 20A, DC INPUT
15. PROTECTION FEATURES
Output protection Electronically protected against overload, no-load and short-circuits
*)
Output over-voltage protection typ. 32Vdc
max. 35Vdc
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.
Reverse input polarity protection included Unit does not start when input voltage is reversed.
Degree of protection IP 20 EN/IEC 60529
Penetration protection > 3.5mm E.g. screws, small parts
Over-temperature protection yes Output shut-down with automatic restart
Input transient protection MOV (Metal Oxide Varistor)
Internal input fuse included The unit is equipped with two internal input fuses (+
line and - line) which protect the unit against internal
short circuits and ground faults. The fuses are not user
accessible. A tripping of an internal fuse is caused by an
internal fault.
*) In case of a protection event, audible noise may occur.
16. SAFETY FEATURES
Input / output separation

SELV EN 62477-1
PELV IEC/EN 60204-1, EN 62477-1, IEC 62103, IEC 60364-4-41
Class of protection I PE (Protective Earth) connection required
Isolation resistance > 500MOhm Input to output, 500Vdc
PE resistance < 0.1Ohm
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.
