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

At a competitive price, it also offers 6A power boost, 9-14A short circuit current, output noise suppression, selectable Single Mode orParallel Mode, small dimensions and easy installation. Due to its wide
range input the unit can be connected to 3-phase electricity networks
worldwide without switching.

Power Boost:Higher current for a short period of time (< 1 minuteor even longer with forced ventilation) without voltage breaking down. Optimum fit to peak load requirements and oversizing of power supplies is not neededanymore.

Overload DesignTM:
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

Connectors and terminals

Two different operating mode options, switchable by plugging the front- Terminals
panel jumper. If the jumper is missing, the unit is set to FUSE Mode. Theunit is preset to Continuous Mode at shipment.
a) FUSE Mode (Switch-off after typ. 5s):
• Jumper is in the 'OVL FUSE mode' position.
Position• When overload or short-circuit occurs for more than typ. 5s, theunit switches off the output.
• Definition of overload or short-circuit: The set output voltage ineach case can no longer be maintained.
• Power Boost and Overload Design™ remain unchanged during the Tightening torquetyp. 5s delay time.
Wire gauge• Red LED flashes at switch-off.
• flexible cable• solid cableb) Continuous Mode (continuous current):• Jumper is in the 'OVL cont. mode' position.
Ferrules• When overload or short-circuit occurs, the unit continuously supplies current (see. diag. 1), no Hiccup.
