EMC andLow Volt.
DirectiveThis compact power supply unit is characterised by the variety of possibilities of application and low system costs. The fact that the externalfuses are no longer necessary is an advantage as it saves cost andspace. The switchable Fuse Mode, the fully specified 2-phase operation and the extremely comprehensive approvals package including
EN60204 make the SL10.300 the unit of choice.

At a competitive price, it also offers 12A power boost, 20A short circuitcurrent, output noise suppression, optional Single Mode or Parallel
Mode, small dimensions, more than 500,000h MTBF as well as easy installation. The unit can be connected to European and American power
supply networks without switching.

To achieve current sharing:• Plug jumper into pos. 'Output parallel use'. This alters the output
V/I characteristic to be 'softer' (25V at 1A, 24V at 10A). The output
voltage can still be adjusted.
• Missing jumper = 'Single Use', i.e. 'hard' characteristic

Overload Behaviour
Efficiency (typ., @ Vout =24.5V)

Two different operating mode options, switchable by plugging the frontpanel jumper. If the jumper is missing, the unit is in the Fuse Mode.
The unit is delivered preset in Continuous Mode.

9291,5Efficiency [%]a) 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.
Advantage: The unit starts reliably even with heavy, non-linear loads(high capacities, DC-DC converters, motors). The high short-circuit current
triggers downstream fuses, and allows for selective configuration of electrical installations.

Hold-up time [ms]b) 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, theunit switches off the output.
• Definition of overload or short-circuit: The set output voltage ineach case can no longer be maintained.
• The capacity to deliver current (PULS Overload Design™) (see diag.
1)
remains unchanged during the typ. 5s delay time.
• Red LED flashes at switch-off.
Feature: With some applications, the Fuse Mode can replace the usual
fusing on the secondary side. The Fuse Mode has closer tolerances thanthermal trips. The release delay time of typ. 5s ensures that motors can bereliably operated.
