voltage problem

Hi to all,I am in the process of shipping my equipment from Australia to Thailand.Here lies the problem, the small village i have chosen to retire in has some terrible voltage drops at certain times of day and night.My equipment is reasonable,My own thoughts is to possibly run my gear through a powerful UPS.any thoughts out there would be greatly appreciated.
You want a voltage regulator and surge suppressor at the minimum.


The average UPS puts out a garbage AC signal. Another possibility is something like this, especially if it can run "in line"
