New 5W low cost AC/DC Converters with 3W footprint

RECOM is releasing two new 5W, board-mount AC/DC converter modules with a choice of industry standard sizes and pin-outs, at very competitive prices. The RAC05E-K series is compatible with existing 3W part footprints and the RAC05E-KT series is in the 'EI30' transformer-pack style. Both series achieve 5W in the same footprint as other 3W parts on the market.

The input range for both is 90-264VAC (130-370VDC) and with standard outputs available in 4, 5, 12, 15 and 24V. The outputs are semi-regulated but stay within +/-5% over line, load and temperature variation from -25°C to +55°C. Both the -K and -KT variants will also operate to +75°C with derating.

Safty certifications include UL/IEC/EN 62368-1 for IT/multimedia and IEC/EN 60335-1 for household applicationa, with reinforced 3kVAC isolation. No-load power consumtion is less than 100mW and light load efficiency is high, enabling significant stand-by power to be drawn without exceeding ErP limits. The RAC05E-KT range meets EN 55014 and EN 55032 'Class B' EMC limits without external components while the RAC05E-K requires just a simple external filter. Full protection is provided against short circuits, output over-voltage, over-current and over-temperature with auto-recovery. Reliability of the parts is high with the K-Series achieving over 1.6M hours MTPF at 25°C and the -KT series achieving over 2.2M hours, backed up by the RECOM 3-year warranty.
