To achieve current sharing the output V/I characteristic can be altered to
be 'softer' (36.6V at 0A, 35.2V at 13.3A). This is done by repositioning an
external bridge connection (without opening the unit).

Life cycle (electrolytics) The unit exclusively uses longlife electrolytics,
specified for +105°C (cf. ’The SilverLine’, p.2).
High reliability, as
• only five aluminium electrolytics and
• no small aluminium electrolytics are used.

Start / Overload Behaviour
Startup delay typ. 0.55s
Rise time appr. 20-80ms, depending on load
Overload behaviour Puls Overload Design (see right-hand diagram)
Advantages:
• 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 13A.
Advantage: Due to the high and continuously supplied overload current the unit starts reliably even with awkward loads (DC-DC converters, motors). No 'sticking' can occur as, for example, with fold-back
characteristics, and secondary fuses trigger more reliably.
