Hey guys,

Finally upgraded to this config. Thanks to all the TE guys for their suggestions.

Intel E7200
Zebronics 7050 mobo
Transend 2 gb ddr2 ram 800
POV Black diamond 500w
Palit 9600 GSO.

Now i need one more advice from u guys.
To protect my pc from voltage fluctuations do i need a stand alone stabilizer or if a buy a UPS APC 500 will give be enuf. I am ok with a back up time of 5-7 minutes.
Thanks in advance
 
I don't think any UPS have built in voltage regulators to protect your PC from extreme fluctuations

If you don't want power-backup, then best to go for Stabilizer

I am using a Syscom 1KVA auto-stablizer which corrects +/- 30V max.

ie if 170W input from mains, output of stab will be 200

if 260W input from mains, output of stab will be 230

Its costs about 1.4K. If you need backup, combine stab with UPS

Mains --> Stab --> UPS --> PC
 
I have a 500 VA manual step up transformer which works from 60V to 260 :ohyeah: . its just the manual part that is annoying. you have to change it like a fan regulator. But planning to get an automatic one ( 2~3KVA) for the whole house soon
 
can anyone recommend stabilizer/transformer

which brand to look at and its costs?

as i don't need any backup but this voltage changes are hell.

just for protection, stabilizer is better or a UPS?

again, do you mean sustained low voltages or continuous ( but less ) voltage variations ?

i don't know!

when my lamp shade flicks, tubelight does not start,router reboots, cooler & AC runs a lower speed. i think that happens due to low-high Voltage.

i don't know how to measure it
 
A UPS will do u no good if the fluctuations are so severe. And most automatic stabilizers also balk at heavy fluctuations.

Some places here in Arunachal have such dirty lines that we usually suggest servos/ cvts but I dunno if u get these in lower power ratings as the 1s I've seen are mostly 1kva+
 
gaurish, does this happen continuously, or only for small intervals of time (< a minute continuous )
 
it occurs small intervals of time .duration is less than a minute

waise whats the difference is the happened more than a minute?
 
the different solutions

1 bigger capacity UPS - will help for small fluctuations , maybe even the occasional bigger ones, but still their relays will take a beating

2) Stabilizer , about the same as a UPS , minus the backup, but can tolerate wider range of voltages, also the better option if you get slightly low voltages continuosly (which might otherwise cause the UPS to switch to backup mode )

3) CVT - the best if you have constant voltage changes , and the ups keeps switching . CVTs can adjust voltage without switching, and can take a lot of abuse WRT fluctuations ( UPS/Stabilizers use relays - the click click sound - which get damaged after so many operations )

4) step up transformers- what you need when you have sustained low voltages , and i mean VERY low voltages which stabilizers cant handle , of the order of 120~180V . these are not suited to handling constant voltage changes though , because they work manually ( there is a knob like a fan regulator to switch voltages)
 
most of the stuff is manufactured locally.

costs , my 500VA stepup cost 1k.

A local electrician should be the best person to ask
