Which UPS to buy ?

[Raccoon]

^^^Thanks for that info. Maybe APC should stop providing batts for the USPs and let the customer buy his own. Anyway, mine wasn't exactly terrible either - lasted some 2 - 2.5 years... but with minimum cycling as most of the time it ran off the Inverter battery during outages.

Seems Microtek isn't a good option. Our old Sukam managed to keep our Amaron battery alive well over 5 years. And the actual cause of death was more out of neglect (low water level). And it wasn't even a tubular battery. Can't recall the float voltages and all now, but whatever it was must have been near ideal, considering the service life of the battery. Another point was that the Sukam dealer offered a significant buy back money for the old inverter. That made the deal MUCH cheaper than the APC option.

Anyone using a UPS to power their LCD TV's ?
I live in an apartment complex and the dg set generally kicks in a minute or two. I just want the ups to keep the tv on and prevent it from abrupt shutdown and restart.

A lot of people recommend pure sine-wave ups which is a costly affair. I was looking for something under 5k.

I want to know if the stepped up square wave is ok for the tv or it can damage it in that minute, in long term use?

I am in the same situation as you.
I used to use a simple APC UPS until it stopped working (actual hardware fault, not battery issue). I never faced any problems.

Even I need to find a replacement. I am thinking of getting a simple cheap UPS as I only need back-up for a few minutes until the DG kicks in.

I am thinking of getting a UPS from an Indian brand called 'Powersafe'. Their cheapest model is around Rs.1800/-. I think it will suit my purpose.

There are quite a few models on Junglee from various brands. You might want to try that.

Why not spend 500/- more and get the basic APC model? Hopefully, a better engineered product.

The sine wave UPS's that I have come across - all need external battery.
Sukam Shiny and APC BI850SINE are pure sine wave models.
Both will cost Rs. 5000+ and battery will be extra cost.

There are reports that flat panel TV's are susceptible to damage due to voltage fluctuations.

I am using a microtek ups 650va and it does the job. Costs 1800 bucks. Luminous & Su-Kam are available for the same price. APC is for around 2300. Whichever of the above ups you buy it will be non-sinewave.

Have 2 questions
1. Does Stepped approximation to Sine wave is same as Sine wave battery? How different is it as I am planning to use for my Plasma TV
2. Also does anybody have a contact for APC reseller in Chennai preferably in Velachery/Adyar areas?

^I am actually considering buying a servo stabilizer. The cost will be around Rs. 2900 (Company: Sollatek). This will be able to take load of upto 4 Amperes.

Stepped sine wave and sine wave have differences.

APC does not have any pure sine wave in the 3K price range. All of the sine wave UPS's will come with separate battery.
