Functional diagrams
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 SL20.100. Regarding the SL20.101 (including PFC) some values may differ.
Start / Overload Behaviour
Startup delay typ. 0.5s
Rise time ca. 20-80ms, depending on load
Duration of switch-on attempts at
• Initial application
on mains
• Subsequent attempts
ca. 1.4s
ca. 0.5s
Hiccup operation at V
out
< ca. 14V
Duration between switch-on at-
tempts
ca. 4s
Electronic current limiting, protects against overload and short circuit:
•V
out
< ca. 14V: Periodical switch-on attempts (hiccup-mode).
Advantages of the switch-on/overload behaviour:
• Safer switch-on into highly non-linear loads with large
starting currents
• Short-term overloads result in current limiting and not in
an immediate shut-down.
• Parallel operation of several units possible.
Proper switch-on performance is obtained.
