RECOM mini power supplies for smart home/office applications

Click2Contact

RECOM’s 2 and 3 W AC/DC power supplies are specially designed to power smart building infrastructure 24/7 by offering compact sizes for easy installation, low standby power consumption (35 mW) and full household (IEC/EN60335), CE (LVD+EMC+RoHS2) and industrial safety certifications (IEC/EN/UL60950).

The RAC03-SER/277 is a regulated power supply designed to fit inside standard wall boxes. Its round shape and low profile of only 11 mm makes it simple and quick to implement smart home/office solutions without extensive renovation works by using the space behind switch plates.

For PCB mounting or even more space-constrained wired applications, the RAC02-SE/277 and RAC03-SE/277 modules with a footprint of only 34 x 22 mm are also available. These power modules deliver isolated, regulated, short-circuit and overload-protected local DC power to run smart building automation applications.

All three power modules deliver isolated, regulated, short-circuit and overload-protected local DC power to run smart building automation applications such as remote sensors and actuators, climate controls, touch-screen interfaces, door access controls, wireless alarm systems, garage door-openers, conferencing and entertainment systems. They have an extra-wide input voltage range of 85 to 305 VAC, so they can cope with worldwide supply voltages as well as abnormal AC power surges and brownouts without losing output regulation. Outputs of 3.3, 5, 12 or 24 VDC are available.

The standby power consumption is less than a twelfth of the requirements of the ErP directive. The modules have 3 kVAC input/output isolation and operate in ambient temperatures from -40 up to +85°C.
