September 20, 200521 yr hi, I bought a DECIDED (Thai brand) stabilizer, it was the cheapest but I bought it because no seller in any shop could give me good reasons to buy a famous brand (imported), which were all double price. Now it works, but I still wonder, what's the risk? Could it explode under my desk? What else? Does somebody else own this brand? Or am I the first one to experience? Thanks for you warnings!!!

October 1, 200520 yr The is always a risk that it could hang up thinking input was 180 when it really was 260 and output 290v but that is not likely. It may fail earlier than the imported model but that also may not happen. It is probably going to be fine. But what made you believe you needed it? Most electronics these days accept a large input voltage range (you mention desk so assume for computer use). Believe the UPS is probably the best investment for most of us.
October 1, 200520 yr Curious as to why you bought a stablizer rather then a UPS (I'm assuming you are using it for your computer since you mention "under my desk")?
October 17, 200520 yr I agree that a UPS is a much better solution but keep in mind that there are different types of UPS's. The basic model is simply an electronic transfer switch & a transverter. This type of unit does not perform any waveform filtering & so does not "stabilise" the electricity. Also, if your intent is to ensure that you have "clean" electricity supplying your apparatus, ensure that your home earthing system is correct & that you also have an MEN link in your main distribution board. This link connects the main neutral to the main earth conductor. By doing so, you can greatly clean your power. In Thailand, this is not generally done which is very dangerous & also allows the neutral conductor to have a floating voltage present (usually associated with harmonics etc). This floating voltage can (and generally does) shorten the life of electronic equipment. Hope this helps.
November 11, 200520 yr Author Sorry, maybe what I bought is called UPS ? It's the box that keeps my computers and tv online when the electricity is down (FAY DAP!)
November 11, 200520 yr yes it sounds like you purchased a UPS ( uninterruptable power supply ) - mine is just a cheapo brand and I have had it for more than a year now with no problems.
November 11, 200520 yr Just curious: what exact UPS did you buy (model name or number)? What price? Could be useful for future reference...
November 11, 200520 yr Just for the record, I've got a Unitec "Unisave UPS On-Line Stabiliser 100%". In Phuket, you need one, especially in the rainy (lightning) season. It doesn't last long when the power goes, but then I'm running the TV, UBC box, lamp, speakers and computer through it. But 15 minutes is enough to finish off what I'm doing and shut down the PC.
November 13, 200520 yr Author Just curious: what exact UPS did you buy (model name or number)? What price?Could be useful for future reference... <{POST_SNAPBACK}> The brand of my UPS is DECIDED, the website is http://www.decided.co.th/ but I've never seen it working! But my UPS is ok, and I paid only 2000 instead of 6000 at least for all the famous imported brands. After a few moths, not yet exploded! ;-)
November 13, 200520 yr Do these cheap UPSs have software with them? Good UPS have software together with a connection (either serial or USB) to the PC which shuts it down properly in the event of a prolonged power failure.

However, my PC has it's own power management, so will go into standby at a highish level of battery life left, and then will hibernate or shutdown at a low level.
November 13, 200520 yr Yes, laptops have a sort of built-in failsafe. UPSs by APC come with software called Powerchute which monitors the UPS and closes files and other good stuff before the power fails completely.

Shut the servers down, sent messages when there was a problem, etc. Could even monitor the batteries statuses from my PC. Good software!
February 17, 200917 yr Author Hi, After 3 years using my Decided UPS it seems that it is now dead, but I guess that it's only about batteries that need to be changed. Any idea where to buy batteries? The manufacturer said to go to Data IT but maybe I could find that kind of battery anywhere ? Thanks.

Pop the batteries out so you get the right size and capacity.

February 17, 200917 yr This is the unit I use. It gives 600W. I use it in switch mode (APS), ie it swtiches in when the power fails and that is good enough to keep my TV/Hi Fi set up running, which is the objective. It can be used in UPS mode, always supplying power from the battery, for a totally smooth transition when the power fails. The battery is 150Ah and can give me 3-4 hours of power. For this type of application it is very important that the battery is a "Deep Discharge" type. A car battery is not suitable.

Take a note of the details of your old one as there are a few different types.

Thanks. 2 batteries in this 1000 va ups, tried to opened, difficult to change the batteries, they (Decided company) charge 1000 thb to pick up the ups, change the batteries and bring it back, so I guess it's honest (but how much would cost each battery at Yaowarat? 100 or 200 thb?)
March 19, 200917 yr The batteries are not cheap so I would advise having them replace for you. Some units are a very tight fit and may require circuit board removal. Believe each Battery is about 600 baht in a place like Data IT. New units are not that much more so expect many people just throw away (unfortunately).
