Described as the perfect power supplies for small IoT devices and industrial controls, Dengrove Electronic Components has released the RECOM RAC05-K series of highly integrated 5-Watt AC/DC converters.

Housed in a 25.4mm x 25.4mm fully encapsulated lightweight plastic case, and with important features such as short-circuit and over-voltage protection built in, RAC05-K modules can fit within tight spaces.

They also meet EN55032 class-B specifications without requiring external filtering components.

The modules are built to withstand harsh industrial or outdoor environments, and can operate from -25°C up to 50°C at full load, or 70°C with derating.

With very low no-load consumption of 75mW, and high light-load efficiency, the RAC05-K series is ideal for powering devices like wireless sensors or communication modules that are always on, with short periods of peak activity.

Available with a single output voltage of 3.3V, 5V, 12V, 15V or 24V, they can also be used to operate relays, data gateways, or building-automation nodes.

The modules feature a 60ms hold-up time at 230VAC input, to maintain a stable output even if the AC-line quality varies.

The RAC05-K series is fully certified to UL/IEC/EN60950-1 and UL/IEC/EN62368-1 with CB reports, CE marked, and covered by a three-year manufacturer’s warranty.
