Stabilizer for 1.5 Ton Split AC - Plz Suggest

zank (zank) 2009-05-18 19:14:00 +0600 #1

I need to buy a stabilizer for my 1.5 Ton AC (old PEL brand with Carrier compressor and condensor)
Voltage fluctuation in my home is quite high, and it may varies ~50 volts, in between 170-210 volts constntly. The compressor gets hot due to running over low voltage and automatically gets tripped due to over heating, and come back cooling again in about 30 mins or so, after the compressor gets normal. This all seems to be due to low voltage drops which makes the compressor to stretch up a bit and consume more Ampere to maintain power output which makes it heated up as a result.

Please suggest which Stabilizers nowadays are good over such a condition and its specs and possible price range.

And also what do you guys think that whether in such a scenario any stabilizer would work or not. There is no use putting up a stabilizer and having no good use of it, if the AC still keeps tripping...

I am also willing to buy used ones if they are in good quality and the owner allows me to check that for one day on my own AC, to make sure it will work over my scenario.

I will go to market today for it, please if anyone can shed his two cents, it would be helpfull for me in deciding.

Do inform us about your market survey as I am also willing to know about it as having similar problems.

Take prices of Universal & Stabmatic stablizer both are famous brands but I have one 7000 Watts stablizer Universal brand for my 1.5 Ton Window AC but at times my KESC breakers tripped due to voltage and Stablizer breaker never trips down.

Do tell the shopkeepr whole scenario.

Thanks

Also in the lookout for information on the same.

Me too looking for to buy a stabilizer for my 1.5 ton AC. Which one is better, Universal or any other like stabimatic? and how much will it cost for a 1.5 ton AC?

get universal , its the best one . . .

amarmak (amarmak) 2009-05-19 15:07:00 +0600 #8

how many watts for 1 ton and 1.5 ton

zank (zank) 2009-05-19 16:04:00 +0600 #9

Market feedback: No stabilizer will work for such a scenario My reliable electronics product dealer from whom I always buy refused me about the stabilizer.
Well, there are many shop owners who are saying that top brands will work just for selling their products. They are not giving any sort of guarantee what so ever.
Just for others info: Universal, Panasonic, Stac are better brands these days in the market. And their 5000 Watts unit will cost around 6+K and that is enough for 1.5 tons AC in normal cases.

Lets hope this KESC thingy gets sorted out in coming weeks...

@zank
we also had this problem of voltage fluctuation.........170V was all we get........!!! :S
and it looked like the AC was running on fan............bought a Stabilizer for 5.5k.............problem solved!!!!!!

zank (zank) 2009-05-19 17:57:00 +0600 #11

@Sam
Is that a 1.5 Ton AC you are talking about above? And which brand of stabilizer did you put on? And its specs plz.
Your words seem to be a ray of hope to me in this condition

Let me see if I can get any stabilizer from any friend for testing purposes ... If it will work then thats not a problem at all...

bhai same prole exist with me

Ac ki voltage 170 say bhi neechay thay first thing i have chaneg my home wiring and in wiring its shows 180 amp

and ac ki wire jo kay meter say aa rhy thy i have chaneg tha wire us say problem removed ho gy

ac heatup bhi nahi hota but i live in lahore

sometimes amperes pooray nahi aa rahay hotay wires main as u live in karachi

and brother one more thing jo pole ki wires hoty hian un main kisi line main ko kah ker sab say uper wali lline main apni wire lagwao because sab say uper current zayada ata ha .

Universal. That is what i would suggest. What you need to ask is if it's one that has a " step up" and " step down" Step up for when the voltage is low and step down for when we sometimes get high voltage, the stabilizer does not let your AC get damaged. What you have described is classic case of low voltage, the compressor trips because of low voltage.

I got Universal for my AC in 2004 and have had no complaints so far and the voltage in my house is almost always low. Don't get tricked by people selling you their products by saying their stabilizer works even if the voltage is 90 or 100. I heard a lot of that stuff when i was buying one.

Every stabilizer has a particular range. It will not work out of it's range. That upper and lower limit will be written on it.

@freed4u
I have direct proper cabling for all of my home ACs. so there is no wiring issue. I also have a selector on my AC so that it can be transferred to any available phase, and all 3 are doing the same problem
@archon2001
Thanks sir jee, cant connect the stabilizer on the main phase as my distribution boxes are two and this could get tricky and also I dont think 7500 watts will be sufficient. I had this idea in my mind but the technician told me that for this a more heavier stabilizer would have to be purchased.
Well I have asked my AC guy to visit my home and see if there is everything well with the AC itself, if AC is fine then I will place a stabilizer.

I have a sort of spare stabilizer of Stac 3600 Watts at my home in excellent condition. Does anybody know if it can work and bear load with the 1.5 tons AC. If you do at simple calculation then 1.5 ton AC needs ~2000 Watts to function. Power=VA

A relative had this problem and he resolved it for good by buying a European Ship-Used Split unit whose compressor operates on 110-220Volts range ... Now he is living happily ever after ...

sam007 (sam007) 2009-05-22 17:27:00 +0600 #18

@zank
its a desi Stabilizer............Power Asia is written on it...!!!
i think it's 5500 Watts (but not sure.......i'll confirm it later)

and we have a 1.5 Ton Orient Split AC.......!!

If I have a circuit breaker do I still need a stabilizer?

zank (zank) 2009-05-22 18:38:00 +0600 #20

Stabilizers usually take care of voltage fluctuation +-20 volts. They have a 10% margin. I have installed a stabilizer for testing purpose, its a 5500 volts some foreign brand, old looking but solid stabilizer. The AC is now running good. But still in times of extreme load i.e. 12 AM to 3 AM in the night it does not work. The stabilizer makes a lot of noise mentioning that it is trying its level bext to stabilize
We (Me, my AC guy and my Electrician) together has hunted down the main culprit though, actually it was the fault of the neutral of the KESC, it was not proper. We have earthed a substitute neutral into the SSGC pipe for temporarily purposes and it is giving better volts now, but still there is fluctuation.
Either we are going to call KESC to solve this neutral problem or we have to dig up a hole about 15 feet down to earth the wire with a small copper plate. I hope then this problem would be solved permanently.
If anyone has any idea about this, then please share your view/experiences. I'm about to work on this in coming days, so anyones two cents would be helpfull...
Thanks to all by the way...
