Power in square CB scheme Data sheet Input: AC 230/115V, DC 240...375V Output: 24-28V/240W Power boost up to 288W High overload current, no switch-off Robust mechanics and EMC Input Input voltage Output voltage DC 24-28V, adjustable by (covered) front panel potentiometer; preset: 24.5V ±0.5% Adj. range guaranteed Note: At DC input, always leave the switch in the 230V position Input current <6A (switch in 115V position) <2.6A (switch in 230V position) Output noise suppression Radiated EMI values below EN 61000-6-3, even when using long, unscreened output cables. DCin at open output 8mA (preserves battery sources) Inrush current Ambient temperature range Tamb Operation: 0°C...+70°C (>60°C: Derating) Storage: -25°C...+85°C 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. Transient handling Transient resistance acc. to VDE 0160 / W2 (750V/1.3ms), for all load conditions. 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 Derating Voltage regulation better than 2% Vout overall Ripple / Noise Efficiency, Reliability etc.* Efficiency Life cycle (electrolytics) The unit exclusively uses longlife electrolytics, specified for +105°C (cf. ’The SilverLine’, p.2). Start / Overload Behaviour Startup delay Rise time Overload Behaviour • Special PULS Overload Design (see diagram overleaf) • 20% power boost – no disconnection, no hiccup if overloaded – high overload current (up to 1.6 INom), Vout is gradually reduced with increasing current. – 12A short-term, at 45°C or forced cooling even continuous Overvolt. protection Parallel operation yes, load sharing available on request Power back immunity Front panel indicator Green LED on front panel Construction / Mechanics* Housing dimensions and Weight • WxHxD • Free space for ventilation • Weight 120mm x 124mm x 102mm (+ DIN rail) above/below 25mm recommended left/right 15mm recommended 980g Design advantages: • All connection blocks are easy to reach as mounted at the front panel. 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 Basic version* N+1 redundancy* Safety Cover* Screw mounting set,two needed per unit
