Compact 10W AC-DC converter for IoT designs

December 05, 2017 // By Nick Flaherty
RECOM in Germany has developed a low cost 10W AC-DC converter series in an industry standard 51 x 25mm (2 x 1in) package.

The 10W RAC10-K/277 converter series are highly efficient PCB-mount power conversion modules with ultra-low energy losses even in light load conditions. This makes them suitable for always-on and standby mode operations in the Internet of Things (IoT) and smart building applications.

IoT systems are equipped with many different sensors exchanging data in real time to enable efficient communication in a smart infrastructure. Most of the sensor nodes in an IoT system operate at least part of the time in a standby state. Therefore, having AC-DC supplies on hand which offer low power consumption across a wide load range is key to energy efficiency. For example, the RAC10-K/277 supplies 300mW to power housekeeping circuits of higher power applications in standby mode while drawing less than 500mW from mains – allowing the higher power application to meet critical ErP standby power regulations.

Designed for IoT and household applications, the modules come with international safety certifications for both industrial and household standards. The extended wide input voltage range from 85 to 305VAC means they can be used worldwide. They provide 100% nominal output power in a temperature range of -40°C to +65°C and offer fully protected single or dual outputs as well as EMC class B compliance without the need of any external components. The 140% peak power capability makes them suitable for high start-up currents
