Inrush current
< 30 A
Inrush current limiting done with a fixed 23R resistor (not a thermistor)
which is bridged after the unit is running, so losses are minimized. That
means no reset time even at a warm-start.

To be fused with a 3 x 10A, B-type 'circuit-breaker' switch based on the
usual thermomagnetic overload sensing principle (used anyway to fuse
the input lines; unit has no internal fuses).

Overload behaviour
PULS Overload Design (see diagram at the right), thus neither

Advantages:
• High short-circuit current, giving large ’start-up window’: unit starts reliably even with
awkward loads (DC-DC converters, motors). No ’sticking’ as can occur with fold-back
characteristics.
• Even longer overload possible as unit does not switch off.

’Signal GND’: Ground terminal for all signal outputs of this unit (not ’Current Balance’)
• Do not connect this terminal to the terminal of this unit (not even across a load: risk
of overload)
• Do not connect this terminal to any output of another unit (not even with ’Signal
GND’ of another unit)
• max. load current: 0.3 A
Signal ground is internally fused by a self-curing fuse (polyswitch)

SL40.301: no switch-over,
charact. as SL40.300, Single Mode
Output current Iout [A]
’Current Monitor’: Current measurement output, usable with
• Voltmeter
1 V per 10 A output current (to ’Signal GND’ output, Rin(voltmeter) > 100 kΩ)
• Ammeter
1 mA per 10 A output current (to ’Signal GND’ output, Rin(ammeter) < 100 Ω)
’Current Balance’: balancing output for current sharing
• For active current sharing at parallel operation interconnect the "Current Balance" output terminals of all paralleled units. The corresponding ground is the
pole. Do not interconnect the "Signal GND" outputs. Exact output voltage regulation is effective when the output current is greater than 0.4A. Current sharing
also works reliable with decoupling diodes and modules for redundancy applications.

’Thermal Alarm’: warning signal at over-temperature
• Signal: High (24 V) at correct operation (no over-temperature). If signal switches to
’low’ and temperature increases further, output current is lowered,
• Ground and permissable load resistance: see ’Power Good’ output
Vout=24V, Parallel Mode

4
’Power Good’: Power-Fail / -Good
• Signal: High (24 V) at correct operation (no overload, over-temp., short-circuit). At
’low’ signal and nominal load, output remains at nominal voltage for at least 5 ms.
• Corresponding ground is ’Signal GND’ output (current source)
• Permissable load resistance: ≥ 300 Ω, e.g. 24V relais, control lamp (no dropping resistor
needed for LED), scoring logic. To get 5V level: connect this output and ’Signal GND’
via 5V zener diode (0.5W) + 1kΩ resistor switched in parallel
Vout=24V, Single Mode

Output for measurements and signalling
’Shut-Down’: Shut-down input: units switches off, if
• Input is connected to ’Signal GND’ (∆U < 1V) or
• +20...28 V Voltage are applied to this input and ’Signal GND’ (max. 20 mA).

• Simple snap-on system
• Sits safely and firmly on the DIN-Rail
• No tools required to remove
or backplane-mounted
