RECOM is releasing two new 5W, board-mount AC/DC product ranges with a choice of industry-standard sizes and pin-outs, at 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 the outputs available are 4, 5, 12, 15, and 24V. 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.
RAC05E-KT range
The RAC05E-KT range meets EN 55014 and EN 55032 ‘Class B’ EMC limits without external components
Safety certifications include UL/IEC/EN 62368-1 for IT/multimedia and IEC/EN 60335-1 for household applications, with reinforced/3kVAC isolation. No-load power consumption is less than 100 mW and light load efficiency is high, enabling significant standby 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 MTBF at 25°C and the −KT series achieving over 2.2M hours, backed up by the RECOM three-year warranty.
low-cost AC/DCs
“These low-cost AC/DCs are an excellent way to upgrade from 3W to 5W in the same footprint or to replace EI30 transformers with additional rectification and smoothing circuitry by just one highly efficient module,” commented Michael Schrutka, AC/DC Product Manager of RECOM,
He adds, “They are ideal for worldwide industrial and building automation, ITE, office, household, IoT, and test and measurement applications, where a semi-regulated output is sufficient.”
