Data sheet SilverLine • Input: AC 230/115V, DC 240...375V • Output: 48-56V/240W • PULS Overload Design™: 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 In <6A (switch in 115V position) <2.8A (switch in 230V position) <37A at AC 264V (Tamb = +25°C, cold start) <62A at AC 264V (Tamb = +50°C, cold start) <2.5A²s (Tamb = +25°C, cold start) <6A²s (Tamb = +50°C, cold start) DCin at open output 8mA (preserves battery sources) 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 Derating Voltage regulation better than 2% Vout overall Ripple / Noise Parallel operation possible; however, no equal load sharing Harmonic current emissions (PFC) according to EN 61000-3-2 Power factor: better than 0.68 at nominal load Transient handling Transient resistance acc. to VDE 0160 / W2 (750V/1.3ms), for all load conditions.

Data sheet Output characteristic (min.) Start / Overload Behaviour 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. – 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 heavy loads (DC-DC converters, motors). • No ’sticking’ such as can occur with fold-back characteristics • Secondary fuses operate...
