RECOM’s E-Series for AC/DC power supply at Rutronik

Compact, cost- and energy-efficient

by gabi

The AC/DC power supply provides the necessary DC voltage for many electronic devices. If these have a standby function, efficiency plays a decisive role to comply with the guidelines for energy consumption-relevant products. RECOM’s E-Series AC/DC power supply modules easily meet these specifications. Thanks to their high efficiency over a wide load range and extremely low energy losses at low loads, the components easily comply with common energy-saving guidelines such as the European Ecodesign Directive Lot 6. In addition to energy efficiency, other key purchasing parameters include compact size, reliability, and pricing. The E-Series and other RECOM products are available at

AC/DC converters, similar to sensors, processors, and actuators, are among the most widely used components. To meet the high demand, RECOM is launching the E-series in a compact form and at low prices – ideal for mass production. Economies of scale allow RECOM to achieve cost savings of up to 50 % compared to similar products without compromising quality. The converters boast high efficiency over a wide load range, short-circuit, overload, and overvoltage protection, and UL/IEC/EN60950-1, 62368-1, 60335-1, and 60601- 1* certifications.

Application examples:

  • Energy-efficient products with Energy Star certification
  • Industrial control systems
  • Smart buildings and smart offices
  • Remote and automated systems
  • Test and measurement systems
  • Standby power supplies in commercial applications
  • Power supplies for panel mounting in enclosures
