III • EN60204 Datasheet Input Input voltage Rated tolerances • Continuous operation • Short-term (30s) at 36V/13A Input current In Output AC 100-120V/220-240V, 47-63Hz, auto select Output voltage DC 36...43V, adjustable by (covered) front panel potentiometer; preset: 36V ±0.5% Adjustment range guaranteed Output noise suppression Radiated EMI values below EN50081-1, even when using long, unscreened output cables. Ambient temperature range Tamb Operation: 0°C...+70°C (> 60°C: Derating) Storage: -25°C...+85°C Inrush current limiting with active bypass of the limiting resistor (NTC). Rated continuous loading with convection cooling: • Tamb=0°C - 60°C 36V/13.3A resp. 43V/11.2A short-term (<30s) 36V/16.6A resp. 42V/14A <18A @ AC 264V (Tamb = +25°C, cold start) <37A @ AC 264V (Tamb = +50°C, cold start) Voltage regulation better than 2% over all <5A2s (Tamb = +25°C, cold start) <8A2s (Tamb = +50°C, cold start) Ripple • Output charact.

EN 61000-3-2 (harmonic current emissions [PFC]) is fulfilled Transient handling Transient resistance acc. to VDE 0160 / W2 (750V / 1.3ms), for all load conditions. Hold-up time Over-voltage protection At 49V ±10%: switch to hiccup mode Front panel indicators: • Green LED on, when Vout = Vout adjusted • Red LED on, when Vout < Vout adjusted Parallel operation To achieve current sharing the output V/I characteristic can be altered to be 'softer' (36.6V at 0A, 35.2V at 13.3A). This is done by repositioning an external bridge connection (without opening the unit). Power Back Immunity Construction / Mechanics Housing dimensions and Weight 220mm x 124mm x 102mm (+ DIN rail) • WxHxD above/below 70mm recommended • Free space for left/right 25mm recommended ventilation 2.5kg • Weight Design advantages: • All connection blocks are easy to reach as mounted on the front panel. • PVC insulated cable can be used for all connections, as the connection blocks are mounted in the cooler area on the underside of the unit.

Data sheet Efficiency, Reliability etc.* Output voltage Vout [V] Life cycle (electrolytics) The unit exclusively uses longlife electrolytics, specified for +105°C (cf. ’The SilverLine’, p.2). High reliability, as • only five aluminium electrolytics and • no small aluminium electrolytics are used. * For further information see data sheets„The SilverLine“, „SilverLine Family Branches“ and mechanics data sheet SL20 Start / Overload Behaviour Startup delay Rise time 10 15 Output current Iout [A] appr. 20-80ms, depending on load Overload behaviour Puls Overload Design (see right-hand diagram) Advantages:...
