This compact power supply unit is characterised by the variety of application possibilities and low system costs. The fact that the external
fuses are no longer necessary is an advantage as it saves cost and
space. The selectable FUSE Mode and the fully specified 2-phase
operation make the SL10.305 the unit of choice.

Higher current for a short period of time (< 1 minute

anymore.
Overload Design
TM
:
Extended output characteristic curve with a high short current at
a gradually reduced output voltage. Unit does not switch off,
when the rated current is exeeded. The high short current reliably
starts heavy loads such as DC-motors or capacitive loads and blows
branch fuses.

Overload Behaviour
Two different operating mode options, switchable by plugging the frontpanel jumper. If the jumper is missing, the unit is set to FUSE Mode. The
unit is preset to Continuous Mode at shipment.
a) FUSE Mode (Switch-off after typ. 5s):
• Jumper is in the 'OVL FUSE mode' position.
• When overload or short-circuit occurs for more than typ. 5s, the
unit switches off the output.
• Definition of overload or short-circuit: The set output voltage in
each case can no longer be maintained.
• Power Boost and Overload Design™ remain unchanged during the
typ. 5s delay time.
• Red LED flashes at switch-off.
b) Continuous Mode (continuous current):
• Jumper is in the 'OVL cont. mode' position.
• When overload or short-circuit occurs, the unit continuously supplies current (see. diag. 1), no Hiccup.
Re-start:
• by pushing the reset button on the unit’s front panel
• by disconnection from mains and re-start of the unit after > 1 min.
or as soon as the red LED stops flashing
• With some applications, the FUSE Mode can replace the usual fusing on the secondary side. The FUSE Mode has closer tolerances
than thermal trips.The tripping delay time of typ. 5s enables heavy
loads to start and thereby avoids unneccassary service activities.
Overtemperature Protection
Continuous Mode Switch-off and automatic re-start after cooling.
FUSE Mode Unit remains switched off after overheating until
restart (also see ’Re-start’ above).
