Input current 3.0 A
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.
Fuse loading 3 A
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).

Start / Overload Behaviour
Startup delay < 0.5 s
Rise time < 0.1 s (40 A, 20,000 µF)
Overload behaviour PULS Overload Design (see diagram at the right), thus neither
switch-off nor hiccup at overload
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.
Output for measurements and signalling
(SL40.301 only)
’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).
’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
’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
’Current Monitor’: Current measurement output, usable with
• Voltmeter
• Ammeter
’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 re-
gulation is effective when the output current is greater than 0.4A. Current sharing
also works reliable with decoupling diodes and modules for redundancy applications.
’Signal GND’: Ground terminal for all signal outputs of this unit (not ’Current Balance’)
• Do not connect this terminal to the
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)
