Data sheet Input: AC 230/115V, DC 240...375V Output: 48-56V/240W Power boost up to 288W High overload current, no switch-off Robust mechanics and EMC Input Input voltage Output voltage DC 48-56V, adjustable by (covered) front panel potentiometer; preset: 48 V ±0.5% Adj. range guaranteed Ambient temperature range Tamb Operation: 0°C...+70°C (>60°C: Derating) Storage: -25°C...+85°C Note: At DC input, always leave the switch in the 230V position Input current <6A (switch in 115V position) <2.8A (switch in 230V position) DCin at open output 8mA (preserves battery sources) Inrush current 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. Rated continuous loading with convection cooling • Tamb=0°C - 60°C • Tamb=0°C - 45°C Output is protected against short-circuit, open circuit and overload Transient resistance acc. to VDE 0160 / W2 (750V/1.3ms), for all load conditions. Efficiency, Construction / Mechanics* Housing dimensions and Weight 120mm x 124mm x 102mm (+ DIN rail) • WxHxD above/below 25mm recommended • Free space for left/right 15mm recommended ventilation 980g • Weight Design advantages: • All connection blocks are easy to reach as mounted at the front panel. Life cycle (electrolytics) The unit exclusively uses longlife electrolytics, specified for +105°C (cf. ’The SilverLine’, p.2). Voltage regulation better than 2% Vout overall Ripple / Noise Overvolt. protection Parallel operation yes, load sharing available on request Power back immunity Transient handling Front panel indicator Green LED on front panel Start / Overload Behaviour Startup delay Rise time Overload Behaviour • Special PULS Over- – no disconnection, no hiccup if overloaded – high overload current (up to 1.6 INom), load Design (see Vout is gradually reduced with increasing diagram overleaf) current. • 20% power boost – 6A short-term, at 45°C or forced cooling even continuous Advantages: • 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 more reliably * *For further information see data sheets „The SilverLine“, „SilverLine Family Branches“ and mechanics data sheet Order information Order number Screw mounting set,two needed per unit
