Unless otherwise stated, specifications are valid for AC 230V input voltage, +25°C ambient temperature, and 5 min. run-in time. They are subject to change without prior notice.
All data is valid for the SL20.110. Regarding the SL20.111 (including PFC) some values may differ (please contact us if necessary).
Start / Overload Behaviour

Startup delay typ. 0.55s
Rise time appr. 20-80ms, depending on load
Overload behaviour
(see characteristic
on the right)
• Power Boost: Short-term (<30s) 125% output
power without voltage drop.
• Electronic current limiting, protects from
overload and short-circuit.
• High overload/short-circuit behaviour
(V
out
<14V) switchable between PULS Over-
load Design and hiccup mode. Switching by
jumper on bottom of the unit; it is not neces-
sary to open the unit for this purpose.
PULS Overload Design™ (continuous current):
• No disconnection/hiccup, thus overloading is possible also for a
longer period of time (load start-up), ideal for parallel operation.
• High overload/short-circuit current due to straight characteristic;
each bias point of the V/I characteristic extends 20A.
Advantage: Due to the high and continuously supplied overload current
the unit starts reliably even with awkward loads (DC-DC converters, mo-
tors). No ’sticking’ such as can occur with fold-back characteristics, and
secondary fuses trigger more reliably.
Hiccup mode:
• Unit switches off when high overload occurs (V
out
< appr. 14V)
with subsequent periodical switch-on attempts (hiccup mode):
– Duration of switch-on attempts:
appr. 0.1s at short-chircuit or appr. 1s at overload
– Duration between switch-on attempts: appr. 1.5s
•V
out
> appr. 14V: The output current is continuous. The V/I charac-
teristic equals that of the PULS Overload Design™; each bias point
of the V/I characteristic extends 20A.
