Q-Series
24V, 3.4A, SINGLE PHASE INPUT
15. PROTECTION FEATURES
Output protection
Electronically protected against overload, no-load and short-circuits *)
Output over-voltage protection
typ. 34Vdc
max. 36Vdc
In case of an internal power supply 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
> 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
T4A H.B.C.
not user replaceable
*)
In case of a protection event, audible noise may occur.

double or reinforced insulation
17. DIELECTRIC STRENGTH
The output voltage is floating and has no ohmic connection to the ground. Type and factory tests are conducted by
the manufacturer. Field tests may be conducted in the field using the appropriate test equipment which applies the
voltage with a slow ramp (2s up and 2s down). Connect all input-terminals together as well as all output poles before
conducting the test. When testing, set the cut-off current settings to the value in the table below.

To fulfil the PELV requirements according to EN60204-1 § 6.4.1, we
recommend that either the + pole, the – pole or any other part of
the output circuit shall be connected to the protective earth
system. This helps to avoid situations in which a load starts
unexpectedly or can not be switched off when unnoticed earth
faults occur.
