The 600va ups is designed for used upto 360 watts(max)
capacity of load.This type of ups can have in-built battery
(12v/7AH)&specially designed for computer systems.Any other
external higher ampere lead-acid batteries are not suitable
for this circuit.If we need to use 40W tubelight,you may use
electronic ballest only, becuse it can have the capacity to
work successfull in both sine wave and square wave outputs
our 600va home CPU ups output rating is square wave this is
not suitable for using coil items. suppose you used coil
items it produce whistiling sound.By this ceiling fan is
comes under coil item, so our home CPU ups is not suitable
for connect ceiling fans.
The following electronic itens are suitable for using this
type of home CPU ups.
(1)CPU(central processing unit)
(2)CRT moniter& LCD,LED monitors
(3)LCD TV
(4)DVD players
(5)40Watts electronic choke tube lights
(6)CFL lamps&smps type electronic items
Note: The time back-up is differ from the wattage used.
eg:20Watts CFL lamps stands glow for 2.30 hours.
