Baby with redundancy CB scheme Data sheet Input: AC 230V/115V, DC 160-375V Output: 24V/2.5A High overload current, no switch-off Quasi-Wide-Range Input N+1 redundancy, RDY relay contact NEC Class 2 Power Supply Input Input voltage Output AC100-120/220-240 V (switchable), 47-63 Hz (85-132 VAC / 176-264 VAC, 160-375 VDC, see also „Output: Continuous Loading“) Quasi-Wide-Range Input: With the switch in the 230V position the power-supply unit operates at low and moderate loads at any input voltage between 95 and 264 V AC (see ’Output’ at the right side). Note: At DC input, always leave the switch in the 230V position Input current < 1.3 A (switch in 115V position) < 0.7 A (switch in 230V position) DC input current at open output typ. 5.3 mA at 110 VDC, 3.9 mA at 300 VDC (preserves battery sources) Inrush current To be fused with a 10A, B-type 'circuit-breaker' switch based on the usual thermomagn. overload sensing principle (used anyway to fuse the input lines). In addition, the unit contains an internal fuse (not accessible) Transient handling Transient resistance acc. to VDE 0160 / W2 (750 V / 1.3 ms), for all load conditions. Rated output voltage For balanced current sharing during parallel operation: Soft characteristic (25.2 V DC ±2% at no-load, 24 V DC ±0.5% at nominal load, almost linear characteristic curve) Output noise suppression Radiated EMI values below EN 61000-6-3, even when using long, unscreened output cables. Ambient temperature range Tamb Operation: -10°C...+70°C (>60°C: Derating) Storage: -25°C...+85°C Switch Continuous loading (at Tamb = -10°C...+60°C, 230V convection cooling), see also diagram overleaf.

Construction / Mechanics* Housing dimensions and Weight • WxHxD • Free space for ventilation • Weight 49 mm x 124 mm x 102 mm (+ DIN rail) above/below 25 mm recommended right 10 mm recommended (front view) 470 g *For further information see data sheets „The SilverLine“, „SilverLine Family Branches“ and mechanics data sheet Design advantages: • Input and output pluggable by means of Combicon® plug connector. • Ensure strain relief of the plug connectors when installing the unit. • Input and output are strictly apart from each other and so cannot be mixed up (input below, output above). Order information Order number N+1 redundancy* Basic version without redundancy* Screw mounting set, two needed per unit

Data sheet Start / Overload Behaviour Start-up delay Rise time – no disconnection, no hiccup if overloaded – high overload current (up to 1.5 INom), Vout is gradually reduced with increasing current. Output voltage Vout [V] Overload Behaviour • Special PULS Overload Design (see right diagram) 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 reliably Output current Iout [A] Further information Output Current...
