The RECOM Power RAC03E-12SK/277 is a cost-efficient AC/DC converter designed for industrial, domestic, ITE, and household applications. It offers a wide input voltage range of 85 to 305VAC and provides a regulated 12VDC output at 250mA, delivering a total of 3 watts of power.
Key electrical specifications include a nominal input voltage range of 100-277VAC and an efficiency of 75% at full load. The converter operates across a wide temperature range of -40°C to 85°C, with full load output power available up to 75°C and reduced output power up to 85°C.
This module features a low profile of 15.4mm and is designed for through-hole mounting in a 4-DIP module package. It boasts 4kVAC input-to-output isolation and meets EN55032 class B EMC compliance without external components, making it suitable for applications in automation control, Industry 4.0, and IoT.
The RAC03E-12SK/277 series holds international safety certifications, including UL/IEC/EN62368-1, CAN/CSA C22.2 No. 62368-1, EN60335-1, and IEC/EN61558-1/2-16, making it suitable for worldwide use.
The input voltage is 85-305 VAC (47-63Hz) or 120-430 VDC.
It provides a regulated 12 VDC output at up to 250 mA (3W).
The input-to-output isolation voltage is 4 kVAC.
The operating ambient temperature range is -40°C to +85°C, with full load capability up to +75°C and derating thereafter.
It is a 4-DIP Module with through-hole mounting.
Typical efficiency is 75% at nominal input and full load at +25°C ambient.
No-load power consumption is less than 75 mW.
