15W and 20W AC-DC Power Supplies for IoT and Smart Home

June 17, 2018 by Paul Shepard

RECOM's latest 15W and 20W ac-dc power supplies are designed for low-power IoT and household applications. Based on the footprint of the compact RAC10-K modules, these new modules feature high-efficiency over a wide load range and minimal standby power consumption.

The RAC15-K and RAC20-K series are PCB-mount ac-dc modules with ultra-low energy losses especially in light load conditions. This makes them well-suited for the always-on and standby mode operations needed for IoT and smart home devices.

Based on the latest developments of integrated power, a next level of efficiency has been reached allowing 20W of power in a modular 2"x1" case size. These ac-dc converters have a universal mains input range of 85Vac up to 264Vac for worldwide use and come with international safety certifications for industrial, AV and ITE as well as household standards.

Both the RAC15-K and RAC20-K are able to operate within a temperature range of -40°C to +80°C and offer fully protected 5Vdc single outputs. The complete range of single output (5- to 48-Vdc), dual output options (12- and 15-Vdc) and wired versions will be available in the Fall of 2018.
