PC Peripherals URGENT!! Stabilizer/UPS!!

Adept
Hi,

My mom was ironing the clothes today when the power went off. Two TV's were on and so was my rig. the inverter could not handle the load and it shutdown, restarted again and then shutdown again.

I reset the inverter but the PC did not post. i got it working again by reseting the CMOS, but i am afraid that this my damage my rig if it happens again.

So, i need a stabilizer or a UPS. my budget is limited to 2K.

Is there a UPS in this range for the rig in my signature?

I think a UPS will be more suitable for my needs and should be able to accept non sinewave input.

Please advice!!!
 
Even that seems less, cause I think you will need atleast 1400VA ups.

any way, why do u use iron on Inverter powered circuit? A good one takes about 1KW, man. It'll drain those batteries very quickly, even if not overload them.
 
yea man, the iron was plugged in by mistake!

But in general, we have voltage fluctuations too.

What will be better for voltage regulation? a UPS or a stabilizer?
 
well, the microtek 800VA, can handle input from 150 volts to 290 volts.
The question is how long do you guys think it will be able to power my rig?

Only the Rig & Modem.

Also, how much is the microtek 1000VA for?? Any ideas?
 
Not many UPS provided voltage regulation

AFAIK, only some highend APC provides that, so a good stablizer is your best bet if you don't want any backup

Thats what I am using, 1KVA syscom automatic voltage stablizer, bought for about 1.3K
 
small voltage variations (+/-30V) = CVT based stabilizers

large voltage variations (+/-100V) = servo Voltage stabilizer

neither of these will offer significant protection. you'll need a ups.

I use a manual version of the servo voltage stabilizer + a UPS
 
Hmm, i am still thinking what i need.

We don't have very major fluctuations here. When it happens, it is around +/-50V which i suppose a UPS can handle.(usually -, + rarely)

What happens is sometimes the inverter trips for 2-3 seconds, i need something that will be able to keep the rig running for these 2-3 seconds.

What UPS is needed for the above requirement?
 
any UPS should do the job. I'd recommend an APC though. I had a V guard and the POS never worked as back up, and worse , kept restarting.

got an APC, no worries. Now both my rigs run APC :) - for the same purpose as you. when the step up switches between voltages, the UPS keeps it running. but if you have a bsnl modem, the modem will still restart ( they are hyper sensitive i guess)
 
wattage , erm no idea (UPS come with VA ratings, which need to be much more than the wattage since Power(W) = VA multiplied by power factor ( which is always <1) . You have a monster PSU, so i guess you may need 800VA+

In general the power factor can be taken as 0.6.
 
duration is not an issue here, any UPS should be able to handle 5 seconds ( but you might need to change the relays now and then)

just get a 800VA/1kVA ups depending on your budget and how willing you are to cut it fine :p

^ not helping guys.. tell me how much i need(me= dumb)... 5 seconds back up!!!

You need a UPS. A stabilizer will give you zero backup; theoretically, it will only avoid your rig being damaged by voltage spikes. If budget is a concern, you should buy a 500-650VA UPS (I think APC makes one for around 2.6K) and connect only your 'puter to it, which should give you 10-15 minutes backup for around 300W power draw. Program a power shut off sequence on your keyboard (like CTRL+ALT+S) so that you can switch it off without the monitor.

That's the cheapest, safest and most effective power down, IMHO.

^^500/600 might be too risky, he has a 750W psu :p

Sorry, didn't see that. I would guess a 800-1000VA or greater would be safer. But I would still recommend a separate UPS rather than a stabilizer as sudden power shut-offs (however graceful) and expensive computer components don't mix well together.
