Hold-up time At 31V ± 3%: switch to hiccup mode Front panel indicators: • Green LED on, when Vout > UT, where UT is appr. 2V below Vout adjusted (24V...28V) • Red LED on, when Vout < UT Parallel operation To achieve current sharing: • Plug jumper into pos. 'Output parallel use'. This alters the output V/I characteristic to be 'softer' (25V at 0.4A, 24V at 20A). The output voltage can still be adjusted. • Missing jumper = 'parallel use', i.e. 'soft' characteristic Power back immunity 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. * For further information see data sheets „The SilverLine“, „SilverLine Family Branches“ and mechanics data sheet Order information Order number Construction / Mechanics* Housing dimensions and Weight • WxHxD • Free space for ventilation • Weight 220mm x 124mm x 102mm (+ DIN rail) above/below 70mm recommended left/right 25mm recommended 1.8kg (SL20.110) resp. 2.5kg (SL20.111) Design advantages: • All connection blocks are easy to reach as mounted at 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.
