My Jetstream JTPS31MB can switched between 120 and 240. I would expect that most modern power supplies will have this ability. What you will need is a receptacle adapter. Amazon has a bountiful selection. Seven Three, Michael - K5WRN http://www.qrz.com/db/K5WRN On Sun, Feb 21, 2016 at 7:49 AM, M

This is an interesting question... For 35 years I worked on equipment made in Australia and later France For a transformer made for 60Hz operation and using it on 50Hz the output will be approximately 80% A 50Hz transformer will see a voltage increase of approximately 120% using 60 Hz. Which is wh

Elecraft now sells the PowerWerx switcher after recommending them to any who asked (I did when I ordered my K3), which has switched adjustment for 120/240 V input. Line Frequency is not relevant. This is an RF quiet PS and uses the IEC power cord which you would get locally (standard desktop comput

Kevin, I lived in Germany 1989-91. I didn't find any problems using appropriate voltage transformers. Many power supplies now have a wide input range so you only need to get the correct plug for that area. The frequency difference might cause a problem with some time based devices. Have a gre

I would like to find a power supply for overseas use (Angola). Voltage there is 220v 50 Hz. I will have a step down transformer which will drop the line voltage to 110v but I believe it will still be at 50 Hz. Will this be an issue for most power supplies built for use in the US (110v 60 Hz)?
