Thank you so much brother.
It was very useful and a sea of information.
Out of fear,ive just ordered a vgaurd grand voltino/90 to 290 v,4 amperes for rs.3400 from fk,that was before seeing your message but will take 3 days to arrive.
So,for the installation and the initial usage I shall connect to the zebronics ups.I had a 32 inches full hd connected to the same and had no problem.Since this is a 70 inch tv I became apprehensive but since you've mentioned that you are using a 65 inches tv connected to an ups,that gives peace of mind.
Thanks a lot,a complete peace of mind.
Ok,I shall not use the ups and a tv voltage stabilizer at the same time as you had adviced,ups not in much use since the computer is no longer used otherwise.
There is no inverter connection in this floor of the house.
May be since its a single phase connection,that voltage tanks whenever the a/c is on,conversion to a 3 phase will get rid of this problem??,thanks
