RECOM offers isolated and regulated 2W/3W AC/DC power supplies specially designed to power always-on 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.

The power supplies offer 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 features a low profile of  11mm making it ideal for quick smart home/smart office solutions without extensive renovation works by using the space behind switch plates.

The RAC02-SE/277 and RAC03-SE/277 modules with a footprint of only 34x22mm are also available for PCB-mounting or even more space-constrained wired applications.

A wide input voltage range of 85 to 305VAC allows the units to cope with worldwide supply voltages as well as abnormal AC power surges and brown-outs without losing output regulation.

The modules have outputs of 3.3, 5, 12 or 24VDC, a 3kVAC input/output isolation, an ambient temperature range of -40°C up to +85 °C and a warranty period of 3 years. The stand-by power consumption is less than a twelfth of the requirements of the ErP directive, according to the firm.
