Control systems with many low power nodes, actuators and sensors that are ‘always on’ are often required by intelligently networked smart homes and smart offices. RECOM’s robust and reliable 2 and 3W AC/DC power supplies are specially designed to power smart building infrastructure 24/7 by offering compact sizes for easy installation, very low standby power consumption (35mW) 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 11mm means that it is possible to implement simple and quick smart home/smart 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 34x22mm are also available. 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, touchscreen interfaces, door access controls, wireless alarm systems, garage door-openers, conferencing and entertainment systems.
All of these miniature power supplies have an extra-wide input voltage range of 85 to 305VAC, so they can cope with worldwide supply voltages as well as abnormal AC power surges and brown-outs without losing output regulation. Outputs of 3.3, 5, 12 or 24VDC are available. The stand-by power consumption is less than a twelfth of the requirements of the ErP directive. The modules have 3kVAC input/output isolation and operate reliably in ambient temperatures from -40 up to +85°C. The warranty period is 3 years.
