Single-Phase Power CB scheme Data sheet Input: AC 230V Output: 24-28V / 480W (600W) 91% efficiency Ideal for parallel operation Simple fusing Input Input voltage Output AC 230V, +15%, – 20% 47...63Hz (SL20.300/.301: 3 AC 400/480V, see separate data sheet) Rated Tolerances • Continuous operation • Short term (1 min) at 24 V/20 A Input current Inrush current Inrush current limiting done with a fixed 15R resistor (not a thermistor) which is bridged after the unit is running, so losses are minimised. That means no reset time even at a warm-start. Fuse loading Unit is internally fused (fuse not accessible). For external fusing of unit and for input line protection, use circuit breaker with B-characteristic 10A or slower action, or alternatively T10A HBC fuse. Output voltage DC 24-28V adjustable by (covered) front panel potentiometer, preset: 24.0V ±0.5% Adjustment range guaranteed Output noise suppression Radiated EMI values below EN61000-6-3, even when using long, unscreened output cables.

Front panel indicators: • Green LED on, when Vout > UT, where UT is ca. 2 V below Vout adjusted (24V...28V) • Red LED on, when 14V < Vout< UT • Red LED flashes, when 0V < Vout < 14V Parallel operation At 33V ±10%: switch to hiccup mode To achieve current sharing the output V/I characteristic can be altered to be 'softer' (25V at 0.4A, 24V at 20A). This is done by repositioning a bridge connection (without opening the unit). Efficiency, Reliability etc.* Efficiency Life cycle (electrolytics) The unit exclusively uses longlife electrolytics, specified for +105°C (cf. ’The SilverLine’, p.2). High reliability, as • only four aluminium electrolytics and • no small aluminium electrolytics are used. * For further information see data sheets „The SilverLine“, „SilverLine Family Branches“ and mechanics data sheet Power Back Immunity 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 SL20.100: 1800g SL20.101: 2400g 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.

Data sheet Start / Overload Behaviour Startup delay Rise time Electronic current limiting, protects against overload and short circuit: • Vout < 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. Duration of switch-on attempts at • Initial application on mains • Subsequent attempts Duration between...
