50Hz to 60Hz conversion

Hi, Your idea is basically sound and should work as long as the UPS originally is designed to produce 240V 60Hz and has its own built in timebase. The reason is that the input as long as the voltage matches makes no difference (50 or 60 Hz). By design, the UPS converts the input voltage to DC to charge the internal battery. The battery then powers an electronic circuitry that produces the 240V 60Hz. The input is then isolated from the output in terms of frequency. This is a common design, however, there are some (not many) that uses for its local oscillation sampling from the source and therefore will replicate the input frequency to its output, but very rare; it's better that you know they exist. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards. P.S. The only problem with 50 and 60 Hz is heat buildup which is tolerable and still within safe parameters. The only time the 50/60 HZ makes a big difference is when motors are used, timers such as in the early designs of microwave ovens, washing machines, etc., pumps and other highly inductive consumers. Most electronic devices converts the AC input to DC and therefore the frequency has negligible effect. Of course others may see it differently.

Can anyone please tell me what are the implications for change over from 50 hz to 60 hz system?
