Data sheet • Input: 3 AC 400-500V (2-phase and 3-phase operation) • Output: 24-28V / 240W • Power Boost up to 288W • External primary fuse not necessary • Switchable operating mode (single/parallel) • Switchable overload behaviour options (Fuse Mode / Continuous Mode) This compact power supply unit is characterised by the variety of possibilities of application and low system costs. The fact that the external fuses are no longer necessary is an advantage as it saves cost and space. The switchable Fuse Mode, the fully specified 2-phase operation and the extremely comprehensive approvals package including EN60204 make the SL10.300 the unit of choice. At a competitive price, it also offers 12A power boost, 20A short circuit current, output noise suppression, optional Single Mode or Parallel Mode, small dimensions, more than 500,000h MTBF as well as easy installation. The unit can be connected to European and American power supply networks without switching. Output Output voltage Rated tolerances (at 24V/10A) 2-phase and 3-phase operation • Continuous operat. AC 340...576V resp. DC 450...820V • Short-term (1 min.) AC 300...620V resp. DC 400...890V • Pls. ask for 'application notes’ at operation with DC input voltage. DC 24-28V, adjustable by (covered) front panel potentiometer, preset: 24.5V ±0.5% Adjusting range guaranteed Output noise suppression Conducted EMI values below EN61000-6-3, even when using long, unscreened output cables. 2-phase operation is specified and permissible. Connection to 3 phases is recommended due to reduced component stress. Ambient temperature range Tamb Operation: 0°C...+70°C (>60°C with Derating) Storage: -25°C...+85°C Nominal input voltage 2 AC and 3 AC 400-500V 47...63Hz, suitable for IT power systems Internally fused on each phase. External fusing is only necessary as required for input line protection. Input current (at 24V/10A) Output is protected against short-circuit, open circuit and overload. Inrush current (supply impedance acc. EN61000-3-3) Peak current I2t Rated continuous loading with convection cooling • Tamb = 0°C - 60°C • Tamb = 0°C - 45°C Voltage regulation <2% over all, jumper in ’Single Mode’ position Overvolt. protection Power back immunity EN 61000-3-2 (harmonic current emissions [PFC]) is fulfilled Parallel operation Transient handling Transient resistance acc. to VDE 0160/W2 (1300V/1.3ms), for all load conditions To achieve current sharing: • Plug jumper into pos. 'Output parallel use'. This alters the output V/I characteristic to be 'softer' (25V at 1A, 24V at 10A). The output voltage can still be adjusted. • Missing jumper = 'Single Use', i.e. 'hard' characteristic Hold-up time Front panel indicator: • Green LED on, when Vout > 18V • Red LED flashes after switch-off in the Fuse Mode *For further information, particularly about EMC, Connections Safety, Approvals, Mechanics and Mounting: see data sheet„The SilverLine“ pg. 2 Detailed dimensions: see SilverLine mechanics data sheet SL10.300 Order information Construction / Mechanics* Housing dimensions and Weight • WxHxD • Free space for convection cooling • Weight 89mm x 124mm x 117mm (+ DIN rail) above/below 50mm recommended left/right 20mm recommended 980g 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 on the cooler area on the underside of the unit.
