Data sheet Start / Overload Behaviour Rise time ca. 5-20 ms, depending on load Overload Behaviour Special PULS Overload Design (see diagram overleaf), so in case of overload • high overload current (up to 1.9 l|\|om), Vout is gradually reduced with increasing current. Moreover 20% power boost (6A short-term, at 45°C or forced cooling even continuous) • High short-circuit current, giving large 'start-up window': unit starts reliably even with awkward loads (DC-DC converters, motors). • No 'sticking' such as can occur with fold-back characteristics • Secondary fuses operate reliably Further information...
