5 W AC/DC Converter

In IoT, many sensor and radio communication modules need to be working 24/7 and, therefore, there is a need for efficient, compact, reliable, and economic AC/DC supplies. For exactly these reasons, RECOM Power's has developed a low cost 5 W AC/DC converter in the market's tiniest 1" x 1" package offering an impressive power density of 7.7 watts/inch³.

RECOM Power's RAC05-K series are AC/DC converters specially designed to supply IoT and factory automation applications. Their low no-load power consumption of only 75 mW and constant efficiency down to 5% load make them ideal for "always-on" IoT systems. RECOM Power fabricated these converters into a lightweight fully encapsulated plastic casing taking up only a square inch on the PCB, therefore allowing them to be designed into space constrained applications. These modules provide high performance without any additional components necessary: and due to modern and efficient manufacturing lines, RECOM Power is able to offer them at the lowest cost.

Standard output voltages are 3.3 V_DC, 5 V_DC, 12 V_DC, 15 V_DC, and 24 V_DC with sufficient power to operate relays, data gateways, and building automation nodes. A universal mains input voltage range from 85 V_AC to 264 V_AC makes them suitable for worldwide use. The modules feature a 60 ms hold-up time at 230 V_AC input, which means that missing mains cycles does not affect the output.

These series operate over a temperature range from -25°C to +50°C at full load (up to +70°C with derating) and are output over voltage and short-circuit protected. An EMC Class B filter is built in without the need of any additional components, further saving space and cost. The RAC05-K series are fully certified to UL/IEC/EN60950-1 and UL/IEC/EN62368-1 with CB reports. They are CE-marked and come with a three-year warranty.
