作为电源行业的标准,ATX12V规范对规范电源设计和提高电能效率具有非常积极而重要的作用。作为该规范的最新版本,ATX12V 2.31版与2.3版相比,将去掉的PW-OK信号检测重新加回到规范当中,同时对最小输出的交错负载进行一系列的调整,增加了RoHS标准并提升至最高地位,而更严格的测试标准也提升了转换效率的要求。要求更加严格,也更加符合当前节能减排的趋势,在新规范发布之后得到了各路厂商的鼎力支持。近期,国内的一线大厂长城推出了基于新规范的电源——静音大师400SD。与市售的电源相比,最大特点在于,该电源是ATX12V 2.31版规范中第一款采用主动式PFC设计的电源。
As a standard in the power industry, the ATX12V specification has a very positive and important role in regulating power supply design and improving power efficiency. As the latest version of the specification, the ATX12V 2.31 version resets the removed PW-OK signal detection back to the spec as compared to version 2.3, with a series of adjustments to the minimum output interleaved load, adding the RoHS standard and boosting To the highest status, and more stringent testing standards also improve the conversion efficiency requirements. More stringent requirements, but also more in line with the current trend of energy-saving emission reduction, after the release of the new standard has been the full support of various manufacturers. Recently, the domestic first-tier maker Great Wall launched a new specification based on the power - mute Master 400SD. Compared with the commercial power supply, the most significant feature is that the power supply is ATX12V 2.31 version of the first specification with active PFC power supply design.
