SL10.300

10 A 3-phase Data sheet SL10.300 SL10.309 (Conformal Coated) CB scheme IEC60950 • 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) UL508 LISTED IND. CONT. EQ. 18 WM, 60°C UL60950 E137006 CUL/CSA-C22.2 No 60950 EMC and Low Volt. Directive 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. Input 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 Derating 6W/K 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) AC 400V 15.4A
