RECOM's 20 W AC/DC Converter RAC20E-K/277

     RAC20E-K/277, a 20 W AC/DC converter with high power density in the E-C series of RECOM, is characterized by its OVC III rating, which can operate at an altitude of 2000 meters (5000 meters for OVC II), and a wide operating temperature range (with derating) from - 40 ° C to+90 ° C. Therefore, this device is particularly suitable for severe environmental conditions, such as roadside electric vehicle charging piles, industrial environments, and power supplies in testing and measurement applications. In addition, its high power density is also suitable for general household applications and applications with a nominal voltage of 277 Vac

     The design size of RAC20E-K/277 is only 52.7 mm x 27.6 mm, which is the same as the existing 20 W K series modules, but is compatible with other industry standards through different pin ways. This 20 W AC/DC converter has a high isolated voltage rating of 4 kVac and can operate at full load over a wide input voltage range of 85 – 305 Vac. The device provides 5 V, 12 V or 24 V single output. The efficiency of each output exceeds 80%, and the no-load power consumption is less than 200 mW, which complies with ECO guidelines.

     RAC20E-K/277 has passed UL/IEC/EN 62368-1 and IEC/EN 61558-1/2-16 certification. It can meet the EMC restriction requirements of Class B standard of EN 55032 without additional external components. The standard functions include comprehensive protection against output overvoltage, overcurrent and short circuit. RAC20E-K/277 uses highly reliable components and advanced design technology. At 25 ° C, the MTBF is 830000 hours, meeting the requirements of MIL-HDBK-217F (GB) standard, and enjoys the three-year standard warranty service provided by RECOM.
