Data sheet

This compact power supply unit is characterised by the variety of possibilities of application and low system costs. The fact that the external fuses are no longer necessary is an advantage as it saves cost and space. The switchable Fuse Mode, the fully specified 2-phase opera- tion and the extremely comprehensive approvals package including EN60204 make the SL10.300 the unit of choice.

• Pls. ask for 'application notes’ at operation with DC input voltage.

2-phase operation is specified and permissible. Connection to 3 phases is recommended due to reduced component stress.

Internally fused on each phase. External fusing is only necessary as required for input line protection.

Start Behaviour

Startup delay Rise time

typ. 100ms appr. 5-20ms, depending on load

Overload Behaviour

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.

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.

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, the

unit switches off the output.

• Definition of overload or short-circuit: The set output voltage in

each 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.

With some applications, the Fuse Mode can replace the usual

Feature: fusing on the secondary side. The Fuse Mode has closer tolerances than thermal trips. The release delay time of typ. 5s ensures that motors can be reliably operated.

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

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).
