我国用的是230V/50HZ , 欧美是110V/60HZ.
关于这个问题,我一直以为很好处理, 改跳线就可以啦!
但最近从美国买了台KRELL, 和那边的技术员沟通后发现不这么简单。
这是他的原话:
Since about 1994, American brands like Krell, Mark Levinson, Martin Logan etc. have built-in frequency sensing software that will disable the power supply if the frequency of the AC is not as specified. The voltage is simple. Most modern transformers come with multiple primary windings for all voltages, so any qualified technician can figure out how to rearrange the wires for different input voltages. Unless you know a very good software engineer and hacker who owns very sophisticated equipment to reproduce the software and chipsets, or to hack into the program, you will have to rely on the manufacturer to convert the frequency.
自从1994年左右,美国品牌的Mark Levinson,Krell的一样,马丁洛根等建于高频感应软件,将关闭电源,如果交流的频率不符合规定。电压也很简单。大多数现代变压器所有电压的多个初级绕组,因此,任何合格的技术人员能弄清楚如何重新排列不同的输入电压的电线。除非你知道一个很好的软件工程师和黑客拥有非常先进的设备,重现的软件和芯片组,或攻入程序,你将不得不依靠制造商的转换频率。
