Gmunden – Board-mounted AC/DCs have typically only been available in inconvenient through-pin technology but now, RECOM makes automated assembly easier with parts rated for JEDEC standard surface-mount reflow. The cost-effective RAC03-K/SMT series provides 3W output at 3.3, 5, 12, 15, 18, or 24VDC from a universal AC input of 85 to 265VAC (120 to 370VDC) in a package just 27.7 x 27.83mm footprint including ‘gullwing’ SMT terminations. Height is 19mm. Parts operate to an ambient temperature of 60°C without derating, (50°C for 3.3 and 5V outputs) and to 80°C at reduced power.
Common safety standards, IEC/EN/UL62368-1, EN60335-1, and IEC61558-1 are met, and parts are rated as Limited Power Source, reinforced isolation, Class II, and for over-voltage category OVCII installation at up to 6000m altitude (IEC 60335-1). EMC directive standards are met including conducted emissions to ‘Class B’ with no external components required (floating output). No-load power consumption is typically 100mW and the parts meet Eco-design standards for standby use.
The RAC03-K/SMT DC outputs are regulated and are fully protected against over-current and short circuits. Further enhancing reliability, the series achieves an MTBF close to 2M hours according to MIL-HDBK-217, GB conditions at 25°C ambient.
These high-efficiency, reliable parts are ideal for a wide range of applications including IoT, home/industrial automation, sensor power, and household and monitoring devices, as well as for housekeeping auxiliary power supplies in industrial products.
“We take pride in making our power products easy to integrate into customers’ end-equipment and the RAC03-K/SMT is a perfect example”, comments Michael Schrutka, MSc. AC/DC product managers of RECOM. “The parts can be reflow-soldered, eliminating the need for a costly, extra hand-soldering production stage”.
RAC03-K/SMT parts include a three-year warranty. Samples and OEM pricing are available from all authorized distributors or directly from RECOM.
