APC i had was not a true sine wave model but the back up series and i bought it for Rs 7500 - it was replaced by APC for more than 11 times and the final replacement just blew up in ma face one morning - i am not joking it literally blew up .
From the BR1000IN page :
Input voltage range for main operations
175 - 295V
Input voltage adjustable range for mains operation
160 - 286V
Microtek 800VA :
AVR : 135~300V AC
What i have observed is whenever the powerchute software shows the volatge going below 190V it would go to battery mode and make that annoying beeping sound until the voltage picks up-draining the battery in the process
- if the battery drains often and becomes weak their service engineer says the board inside the UPS also gets affected - i dont know how far this is true - may be thats why mine went dead so many times with frequent voltage fluctuations aand the draining who knows
.
The microtek its not a problem in this scenario its AVR works without switching into battery mode and drainingthe battery - in all these 12 months i havent seen the microtek going to battery mode not even once for low voltage
- add to that the power situation in tamil nadu has worsened beyond belief - 5 powercuts daily with lot of voltage fluctuations - my earlier APC ups wouldnt last a week in the present situation .
Overall a 2.4K product doing what a 7.5 k product couldnt - that too pretty well - so am a happy customer
.
And for the bad reviews on APC you just have to search for it - lot of people have burned their fingers by going the APC way
here is an example from techenclave itself :
this from another forum :
a petrol pump i know has replaced its APC inverter for more than 6 times - there are people who have smoked 20k+ going the APC way
.
Yeah that was ma biggest worry as most people here said that i will suffer from that incompatiblity - No issues with the VX450 - if i were you i would go for the 1000VA model just to be safe
