Eastern Japan Voltage 100 Vac @ 50Hz. (Tokyo, Kawasaki, Sapporo, Yokohoma and Sebdai) Western Japan Voltage 100 Vac @ 60Hz. (Osaka, Kyoto, Nagoya, Hiroshima)
I also agree with Tania and the brown-out conditions that exist in Japan. It is my understanding that 90 Vac is quite common, personally I would test down to 85 Vac at 50/60 Hz at the maximum specified operating temperature with high humidity conditions present. > -----Original Message----- > From: Grant, Tania (Tania) [SMTP:[email protected]] > Sent: Wednesday, November 03, 1999 4:57 PM > To: [email protected]; '[email protected]' > Subject: RE: 90V & 47Hz - Is this a realistic combo > > > Ages ago when I worked at another company that shipped products to Japan, > their unwritten rule was to design in power supplies that operated without > problems at 85 Vac, and that had better be designed/tested down to 80 Vac, > because of the continued brown-out conditions in Japan.
