Can I use voltage stabilizer instead of a UPS in computer?

I have a UPS but it is not working. So instead of a UPS can i use a voltage stabilizer for merely stabilizing the voltage and not giving me backup. I just want a steady voltage for my computer.

VOLTAGE STABILIZER
Voltage stabilizer just provides the stable or constant voltage as output in case of fluctuating input voltage. suppose if a T.V requires 120v ac but if the input voltage is varying between 220v to 240 v , then off course the T.V required input voltage may also vary around 115 to 125 v ac . This leads to burn out few sensitive electronic components hence by using a voltage stabilizer we can provide a constant voltage of exactly required 120v ac besides changing in the input voltage(i.e 220 to 240v ac).
U.P.S
u.p.s stands for un-interrupt power supply . That is the device which provides the back up( provides o/p in the absence of input) to prevent the sudden power shut down which comes into account.
example- a computer etc.
so what i say is the voltage stabilizer is different from a U.P.S, hence it should not be used in place of ups, which fails to give back up to the computer and finally turns off the computer in case of any sudden power cut , which leads to abnormal shut down of a computer

No....Both are different ... so don't use like that.........

no ways as there are 2 problems
1stly the backup and secondly voltage stabilizer may not provide protection against noises and surge protection coming from ur ac mains

The basic component that is present in an UPS is a battery.Similar to the one's we've in our vehicles, of course with some additional circuitry to provide controlling actions.

A voltage stabilizer has a component that can maintain a constant voltage in spite of the variation in input current or load like Zener Diode.A stabilizer can maintain the constant voltage though it cannot supply the power of its own.

Ups generally have this kinds of circuits inbuilt

But you can use it other way round....ups in place of stabilizers...

I have different issue. Having voltage fluctuations in supply. Will my UPs address this? i.e voltage stabilization and power supply. or I need to put aditional stabiliser in series of UPs?

Hi.
Practically, the UPS systems are rated for a specific range of input and output voltages. i.e: If you have single phase UPS then generally it would work from 200-240 V AC input. The tolerance range on input and output side depends upon the manufacturer of UPS and its internal circuit. (Check name plate details on your UPS for input and output voltage range)
If the source/supply voltage fluctuations at your place are within the input range limits of UPS, then the UPS would work without any hiccups. For input/source voltage fluctuations more than the defined limits of UPS voltage input range, you'll need an extra voltage stabilizer at input of UPS (in series and before UPS)

Hope this helps.
Thanks.

I purchase a 7.0 kva Voltage stabilizer which I connect in series with home inverter Exide 850va pure sine wave. But the problem is stabilizer relay not working properly (at the time of change in load/input voltage, mains cut due to long changeover time in relay)
When I remove the home inverter the proble is solved. Now my stabilizer working properly.
My area line voltage is app 167V to 180V during 5pm to 3.0am and the load connected to my inverter suffers for proper voltage.
What should I do?

Stabilizers mainly provide voltage regulation, but do not provide backup in case of power outage. Whereas good quality UPS does both. In case you have no power outage issue in your area then you can use a stabilizer to provide a regulated supply for your computer.

you have power cuts and voltage fluctuations then your PC motherboard can get damaged. its always recommended to connect ups with PC for voltage and power off protection
