Input: 3 AC 400V Output: 48...56V / 480W (600W) 92% efficiency Ideal for parallel operation Simple fusing Output 3 AC 400 V, – 15 %, + 20 % 47-63 Hz, suitable for IT power systems Rated tolerances 340-479 V AC • Continuous operation • Short-term (1 min) 300-550 V AC at 48 V/10 A Input current Inrush current Inrush current limiting done with a fixed 47R resistor (not a thermistor) which is bridged after the unit is running, so losses are minimised. That means no reset time even at a warm-start. Fuse loading Input Input voltage Output voltage 48...56 V DC, adjustable by (covered) front panel potentiometer, preset: 48.1V ±0.5% Adjusting 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 Rated continuous loading with convection cooling • Tamb=0°C - 60°C 48 V / 10 A (480 W) resp. 56 V / 9 A (504 W) • Tamb=0°C - 45°C 48 V / 12.5 A (600 W) resp. 56 V / 11 A (616 W) short-term (< 1 min.) also at 60°C permissible To be fused with a 3 x 10A, B-type 'circuit-breaker' switch based on the usual thermomagnetic overload sensing principle (used anyway to fuse the input lines; unit has no internal fuses). Harmonic current emissions (PFC) Transient handling Active transient filter incorporated, so transient resistance acc.to VDE 0160 / W2 (1300 V / 1.3 ms), for all load conditions. Hold-up time Efficiency, Reliability etc.* Efficiency better than 2 % over all < 50 mVPP (i.e. < 0.1 %) incl. spikes 20 MHz bandwidth, 50 Ω measurement Over-voltage protect. At 61V ± 7%: switch to hiccup mode Front panel indicators: • Green LED on, when Vout > UT, where UT is appr. 4 V below Vout adjusted (48 V...56 V). • Red LED on, when appr. 28 V < Vout < UT. • Red LED flashes, when 0 V < Vout < appr. 28 V. Parallel operation To achieve current sharing the output V/I characteristic can be altered to be 'softer' (48.8 V at 0.1 A, 48 V at 10 A). This is done by repositioning a bridge connection (without opening the unit). Power Back Immunity Voltage regulation Life cycle (electrolytics) The unit exclusively uses longlife electrolytics, specified for +105°C (cf. ’The SilverLine’, p.2). High reliability and lifetime, as • only four aluminum electrolytics and • no small aluminum electrolytics are used. * For further information see data sheets „The SilverLine“, „SilverLine Family Branches“ and mechanics data sheet Construction / Mechanics* Housing dimensions and Weight 220 mm x 124 mm x 102 mm (+ DIN rail) • WxHxD above/below 70 mm recommended • Free space for right/left 25 mm recommended ventilation 1.8 kg • Weight Design advantages: • All connection blocks are easy to reach as mounted at 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.
