Baby SilverLine with 2.5 A Input: AC 230V / 115V Output: 24V / 2.5A High overload current, no switch-off Quasi-Wide-Range Input Robust mechanics and EMC NEC Class 2 Power Supply Data sheet 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 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 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 Continuous loading (at Tamb = -10°C...+60°C, 230V convection cooling), see also Diagram overleaf.

Overvolt. protection Parallel operation yes; current sharing available on request Power back immunity Front panel indicator Green LED, goes out at Vout < 18V 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) – no disconnection, no hiccup if overloaded – high overload current (up to 1.5 INom), Vout is gradually reduced with increasing current. 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 Description (Basic version*) (N+1 redundancy*) (Screw mounting set, two needed per unit) 1/2
