This is done by repositioning an external bridge connection (without opening the unit). Construction/ Mechanics* 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. Housing dimensions and Weight 220mm x 124mm x 102mm (+ DIN rail) • WxHxD above/below 70mm recommended • Free space for left/right 25mm recommended ventilation 1.8kg • Weight * For further information see data sheets„The SilverLine“, „SilverLine Family Branches“ and mechanics data sheet SL20 Order information Power Back Immunity Design advantages: • All connection blocks are easy to reach as mounted on the front panel. • PVC insulated cable can be used for all connections, as the connection blocks are mounted in the cooler area on the underside of the unit.

Start / Overload Behaviour Start-up delay Rise time appr. 20-80ms, depending on load Outupt voltage Vout [V] 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 10A. • Advantage: Due to the high and continuously supplied overload current the unit starts reliably even with awkward...
