Don't buy a new miner only to under-clock it, you are essentially throwing money away if you don't gain any efficiency on it (which you can't unless you are able to provide lower than 12V through PSU)
You may be stuck buying a 1600w PC PSU which will take 120-240v.
I can't say how well they will take constant voltage changes, but if it's within the range they will certainly work.
Look up an eVGA 1600w G2, they're around $360 USD.

my method of underclocking to freq 462 and buying the evga 1300 g2 is better
he saves 160 usd maybe more.
he runs at 9.9 th vs 12.0 th
so he loses 2 th.
gear is much quieter much cooler
if it is hot desert he is well off.
2 th is going to earn 160 usd in about 7 months. So he would be ahead of the game for the next 7 months. with the evga 1300 g2 and a downclock.
plus much much much much less noise.
and less heat

hi,
bitmain APW3-12-1600-B2 have this note (The PSU cannot be used in countries with a mains power voltage lower than 205V. The PSU will not start below this voltage. And power cord is not included, please find one with at least 16A from your local market.)
i have free electricity but its very bad which moving all the time between 185V to 220V ( using voltage stabilizer! )
without stabilizer it moving between 145V to 180V
now, what is the best solution for this situation

A) tell us what country So I can figure what psu will ship to you.
B) do not use the APW3-12-1600-B2
C) read on underclock of the s-9
https://bitcointalksearch.org/topic/s9-ln-1534854
D) if you are willing to run at an underclock the s-9 at freq 462 uses 1080 watts at the wall and hashes close to 9.9th
E) all of the above means the EVGA 1300 g2 a 1300 watt psu should do the job if you clock at freq 462
it uses 110 volts to 240 volts let me find the exact number make that 100 to 240 volts.
