RECOM’s new RAC05-K series are low-cost 5W AC-DC converters in a 1′′ x 1′′ package which offer high power density of 7.7W/in3 and high efficiency at light and full load.

The RAC05-K converters are intended for use in Internet of Things (IoT) devices and factory- automation systems that include sensors and communications nodes that are always on. These systems are typically in a quiescent state for long periods, and so require a power supply which draws little power when supplying light loads. The no- load power consumption of the RAC05-K parts is only 75mW and efficiency remains above 70% even when the load falls to as low as 10% of the converter’s maximum power output.

The RAC05-K modules provide a complete offline power supply with no need for external components. They operate from a universal mains input-voltage range of 85V to 264V AC, and provide standard output voltages of 3.3V, 5V, 12V, 15V or 24V DC, giving sufficient power to operate relays, data gateways and building- automation nodes.

The modules feature a 60ms hold-up time at an input of 230V AC, which means that missing mains cycles do not affect the output.
