Hi,
Where can I purchase an ONLINE, 5 KVA, 1 Phase UPS with 12 V battery on input side? The batteries should be outside and back up time is required for 30 minutes.
In market they have machines with 192 V input and in some cases 48 V.
Thanks to all participants for such fruitful discussions.
The ambient may be as high as 40 degree Celsius on some summer days.
Looking at to serious heat accumulation possibilities I am evaluating possibilities of installing heatsinks on 4 sides.
Sorry for getting late in thanking you all.is
Hi,
I have a 750mmDx600mmWx450mmH IP 67 enclosure of SS 304 and it has one 5KVA online UPS plus 4SMPS inside.Total power input is 3000Watts.Willthe heat dissipation be a problem? The enclosure will be used in open air.
Thanks IRstuff for your reply.
However I am looking for some sort of compound (may be a 2 part or 3 part system) which after spreading on the potholes hardens and adheres with the ground firmly. It's OK even if it lasts for say month.That also will save a lot of hardships.
During rainy season in India we face enormous problems due to potholes on tarred roads.At some places they are as big as 5 feet diameter and 1 foot deep at the center. Needless to say the traffic moves at snails pace, two wheeler meet with accidents, cars and trucks get damaged their axle breaks...

The air offers resistance to the moving part and hence if we put in a vacuum chamber there wont be any air and no air resistance and so less loss of power and so increase in ever all efficiency of the "gravity generator".
The output power is the one we get at the shaft of the generator.
The...
Thanks to all those who responded.
based on some knowledge read somewhere I have the following concept:
3 arms made out of rods at 120 degree with each other in a vertical plane(in wind mill they have the blades).
These arms shall be fitted with 3 heavy balls at their ends (calculations needs to...
Hi Peteltt33,
Just check whether the brush assembly of the trouble side has become loose ? On ships I used to face this problem sometimes. ( I mean in the 70's when there were good number of d.c.motors)!
