전력 변환 과정에서 발생하는 손실이 전반적인 비용 증가를 초래하기 때문에 효율성은 전원 공급 장치 설계에서 항상 주요 목표였습니다.
큰 수의 힘
In 2004, the US EPA’s ENERGY STAR programme estimated around 10 billion power supplies in use worldwide — across computers, servers, printers, televisions, phones and more. That predates smartphones and the connected-device era, so the figure today is far higher.
Efficiency back then was poor. The same assessment found many designs converting only 30 to 60% of the power they drew, and the prevailing industry design guide for PC power supplies required just 70% efficiency at 50% load.
Certified designs today are in a different class. 80 PLUS® Titanium requires 94% at 50% load on 115 V, and the newer Ruby tier 95%. Cybenetics Diamond, which averages efficiency across the full load range rather than fixed points, requires 95% or higher on 230 V. Seasonic’s PRIME ENTERPRISE RX-1600 is the first ATX power supply certified 80 PLUS® Ruby at 115 V and 230 V.
At the same 50% load point, that is 70% to 95% in twenty years. Across billions of units, that difference is a substantial amount of electricity no longer lost as heat.
자격증의 역사
Until the early 2000s, power supplies had no efficiency certification, and it was not until 2004 that the first initiative to create an efficiency standard emerged.
The 80 PLUS® program was created in 2004 by Ecos Consulting, an energy efficiency firm, and is today administered by CLEAResult, which acquired the program through Ecos’s successor company.
Sea Sonic partnered with Ecos Consulting at the time to work out uniform efficiency standards, and in 2005 became the first manufacturer to bring the world’s first 80 PLUS® certified PC power supply to market (the Seasonic SS-400HT). Since then, 80 PLUS® certified power supplies have become a de facto component in PC systems.
효율성 이해하기
효율성 인증은 소비자가 전력 공급의 효율성을 파악하는 데 도움이 됩니다.
효율 백분율은 출력 전력을 입력 전력으로 나누어 구하며, 이 수치가 높을수록 전원 공급 장치의 효율이 높습니다. 변환 과정에서 손실되는 입력 전력은 열로 변환됩니다.
Higher-efficiency power supplies often require more advanced designs and components. However, an 80 PLUS® rating specifically certifies energy efficiency, not overall build quality. During certification, the power supply is tested at several load levels, including 100% of its rated output, to verify its efficiency under the defined test conditions.
Cybenetics
Cybenetics PC 하드웨어 테스트 및 인증 전문 기업입니다. 최종 사용자가 시스템에 사용할 전원 제품을 구매할 때 더 명확한 정보를 얻을 수 있도록 전원 공급 장치 테스트 및 비교 방식을 혁신하기 위해 설립되었습니다.
측정의 중요성
The basic test methodology is that Seasonic doesn’t take only three or four measurements to define the efficiency or noise output of a PSU. On the contrary, it is applied more than 1450 different load combinations, starting from a minimal load and up to a full one; we get the average efficiency and noise readings, which define the PSU’s efficiency and noise ratings.
This provides Seasonic with a complete operational map of the PSU, allowing us to evaluate not only efficiency and noise, but also voltage regulation, ripple, and other important performance data.
