It's all about the amount of iron in the power transformer.
The higher the frequency, the smaller the transformer can be. That's why
aircraft used 400 Hz. Less iron. Less weight.
That's also why switching power supplies are so much smaller. They
operate at much higher frequencies.
In general you can power 50 Hz equipment from 60 Hz. But you have to be
careful about powering 60 Hz equipment from 50 Hz - the transformer may
saturate. Don't even think about powering 400 Hz equipment from 50 Hz or
60 Hz.
There is nothing inherently /bad/ about 50 Hz.

OMG...in almost the entire world PSU's are working bad because of the 50Hz?
What about 400Hz from airplanes?

Thanks for the confirmations. The step-up from
110->220 should be pretty
easy to deal with, but I'm wondering how tolerant this supply would be of
60Hz A/C. I suppose if it's a direct clone of the Dec Pro's supply it
might be OK, I'll have to compare :).
Typically, power supplies operate better at 60Hz than 50Hz, particularly
the old linear supplies. Modern switching supplies are very tolerant of
under and over voltages with a wide range of frequencies. My bet is it'll
run just fine with 60Hz.
