Re: Japan mains voltage
Standards aside, one other practical point to consider (all countries), the +/- 10% (or whatever) that may be quoted by (or required of) the utility company applies only to the point at which they deliver to their customer. There will then be an additional volt-drop within the customer's installation, from the utility supply point to the equipment connection. In a large industrial facility (factory), this may be significant. The volt-drop might tend to be higher in 100V than 230V systems. Also, in many cases, the utility will be providing supply to a building or an entire factory site, at MV voltages, and the customer will be responsible for transforming to 100V (or 110/115/120/230/240V, etc.), and they will usually be free to decide whether they want to bother keeping to the +/- 10% range or not. best regards, glyn -- TUV Rheinland of North America, Inc.

Yes, we have experienced similar problems at some sites in Japan. This is one of the reasons why we specify our power supplies (we buy them in) to cover the range from 85 V.

RE: Japan mains voltage
In designing power supplies, it is common to use nominal mains voltage +/-15% (e.g. in North America, 115 +/-15%, or 98V to 132V) as a design guideline. The same +/-15% is generally true for European 230 V designs. Thus, using +/-10% for Japan seems a little skimpy. Given the rather odd collection of voltages, line frequencies and power systems in use there, if it were me, I'd allow for AT LEAST +/-15%. Bob Wilson TIR Systems Ltd.

RE: Japan mains voltage
Hello Eric, Some companies have environmental test programs that subject their products to all types of power line conditions that are not covered in regulatory requirements. As far as line voltage tolerance testing, this depends on the specifications you publish externally for your products. However, what tolerance you test to internally may be greater than what you publish with a product specification. It just so happens, when I was with the old Hewlett-Packard, we usually tested to +/- 12% for test and measurement products when the published tolerance was +/- 10%. However, these products were intended for light industrial and laboratory environments. Finally, to the best of my knowledge, I haven't heard of Japanese line voltages dropping below 90 Vac.

Japan mains voltage
I can only speak for ITE products per IEC 60950. Note that this standard requires testing for safety at -10% and +6%, or 90V to 106V for Japan ITE rated at 100V only. Note that this must be done for both 50Hz and 60Hz, both of which are used in Japan. I am not aware of any stated 85V test requirement for Japan, and would be surprised if long term 15% voltage drops were common in Japan. As in any country, there can be momentary brown outs where the voltage may briefly sag to even lower values.

RE: Japan mains voltage
One of the Japanese islands also has a 50Hz power grid. Apparently it's a real dog's breakfast there, as far as AC power systems are concerned. The voltage is 100 V, not 110V (as the original poster had mentioned). Bob Wilson TIR Systems Ltd. Vancouver.
RE: Japan mains voltage
The standard voltages are 100 V (the standard outlet) and 200 V, and one half of the country uses 50 Hz while the other half uses 60 Hz. The division is North and South, but I don't recall which half uses 50 Hz.

Much of Japan is 100V 50Hz (worst case for transformers). Japan approval should cover 50/60Hz. Hotels generate a 120V 60Hz for US appliances. The 200V supply is more complicated. I had a JEOL electron microscope that wanted 3-phase 200 volts. They would not let us run it on 208V 3-phase and we had to install an elaborate conversion network.

RE: Japan mains voltage
Darren - the Japan mains voltage in the range you request is 100V. As I understand it, though this is open to correction, Japan has both 50Hz and 60Hz distribution systems, depending upon where you are located, even on the large island. I do note, however, that the US Dept. of Commerce's publication, Electric Current Abroad, indicates only 50Hz. I have other sources that indicate both 50Hz and 60Hz. Regards, Peter L.

Re: Japan mains voltage
Darren, The mains voltage in Japan is 100V +/- 10%. Half of Japan is supplied from a 50Hz system and another half is supplied from a 60Hz system.

I read in !emc-pstc that Darren Pearson dar...@genesysibs.com wrote (in 001a01c1ba0c$c7243fa0$0a00a8c0@darrendesktop) about 'Japan mains voltage', on Wed, 20 Feb 2002: Can anyone tell me what the mains voltage is in Japan, I think it is 110V but I do not know the frequency. It's 100 V, and half the country has 50 Hz and half has 60 Hz. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero.

RE: Japan mains voltage
According to World Electricity Supplies from BSI, voltage is 200/100, 60 Hz. We have certainly produced 100V 60 Hz specials for Japan.
