To reduce its carbon footprint an electronic product shall have a minimized power consumption in all operating modes. Limits are defined by serveral national and international authorities.

Test method

Measure the power consumption under different conditions

  • Voltage level
  • Frequency
  • Operating modes (e.g. sleep, idle, operating,...)

Relevant Internations Standards

  • Energy Star - Requirements for computers, displays, servers, ...
  • IEC/EN 62018 - Power consumption of information technology equipment (ITE)

Worldwide regulations for energy efficiency of ITE

  • Europe: Implementing Directives of EUP
  • Japan: Top Runner Program
  • Korea: e-Standby Power Program
  • China: Energy Efficiency of Computer Monitor
