I have a 600VA UPS for computer only. It holds for
20minutes only.
1. Can it be upgraded for longer period.?
2. Can it be used for one ceiling fan and a tube light? If
yes, how to upgrade?
Answer Posted / prajwal
Well, I definitely wouldn't recommend anyone to do anything to increase their battery backup other than that is provided by the ups. Also there is one possibility that can be done. Connecting two 12v 7.5Ah batteries increase the current in the circuit but keeps the voltage same(one of the most important thing when working with batteries).And Ah of a battery is Amperes per hour,which means that a 7.5 Ah battery can provibe upto 7.5 amps of DC current depending on the load. I recommend this only if your load requires more power than the ups supplies l,keeping in mind that the ups is also able to produce the required power.

L.A. (Lightening Arrester) is located at a place from where transmission line enters the transmitting substation. So L.A. (Lightening Arrester) is the first equipments which has to encounter with lightening, high voltage surges and switching surges. It has to absorb energy of lightening, high voltage surges, and switching surges. L.A. (Lightening Arrester) is made up of layers of semiconductors. If these layers can not tolerate energy released by lightening, high voltage surges, and switching surges the L.A. (Lightening Arrester) blasts.
