I checked it, and the bulb does not get dim, at least not for about 5 minutes. The current through batteries when the UPS is connected to AC is about 0.10A.
@Wazir.
Thanks. I will check the variable to confirm if it increases the output voltage, but then I guess the fix isn't going to be...
The battery is a sealed one, so I guess I would have change one or both if I can make sure that the fault is with batteries. The one at 13v has the main connector that goes to the transformer (a really thick cable because of high amperes), and this connector seems to have burnt a bit too. The...
Hi.
I have a 1000va UPS that I use for my Computer as their are numerous blackouts in my area. Recently I moved to a new location and for a few days initially, the mains voltage kept dropping too low (~170-200v instead of 220/230), during which time the UPS would go to the battery, but after...
