I have an UPS and a voltage Stablizer, normally ac supply is 220volts in our country, but having some low voltage issue. Multimeter showls input voltage is only 132volts. Stablizer is operating but ups does not. I need to know what is the minimum input voltage for a normal stablizer and UPS. can ups amplifiy voltage or stable volts like voltage stablizer?
That's the range I wanted to know, thanks a lot. I want to know too that, is there any way to make it working around 130volts? as voltage stabilizer is working nicely!That's the range I wanted to know, thanks a lot.

you will need a reducing transformer 220volts to 120 volts, you can find one at Radio Shack or Fry's Electronics., European countries uses 220volts, and the plug configurations are different from those of the USA.it is recomended to take one of these transformers with you when you travel abroad.
We all use many devices and equipments that run on electricity. For all these to function properly they need uniform power supply (constant flow of electricity). As the electric supply in many countries is not uniform there is a need for a device to correct it. There are many such devices available in the market today. For example UPS (Uninterrupted power supply), Voltage Stabilizer, Constant Voltage Transformer are such devices available today.<br />
<br />
<b><u>Why buy a UPS?</u></b><br />We can never guarantee that we will get constant power. The power supply always has fluctuations. Surges, Spikes, Brownouts, Blackouts and Noise can damage your electrical appliances especially your computer. To prevent this from happening you need a device that does power conditioning. Electricity has to be uninterrupted. If the voltage is higher than the specified level then it is 'Over Voltage'. If the voltage is lower than the specified level then it is 'Under Voltage'. Both Spike and Surge come under 'Over Voltage' category. But there is a small difference between spike and surge. If there is very high voltage for an instant but comes back to normal immediately then it is called 'Spike'. If there is very high voltage for a slightly longer period then it is called 'Surge'. If the voltage is dangerously reduced to very low within a short period of time then it is called 'Brownout'. When this happens, the computer can be seriously damaged. If the power supply is totally cut then it is called 'Blackout'. Noise can mix with electromagnetic or radio waves or any signals. This is called 'Line Noise'. This may also reduce the voltage level to very low within a short period of time.<br />
<br />
<b><u>How can the UPS provide power when the main electrical supply is cut?<br /></u></b>A UPS has an internal battery. With this battery charger, an Inverter is also present. The inverter converts the 'Direct current' supplied by the battery to 'Alternatinc current' as required by the computer. When there is electrical supply the charger in the UPS charges the internal battery. When there is a power cut, the battery kicks in to supply the DC which is converted to AC by the inverter and power is supplied to computer.<br />
<b></b> <br />
<b><u>What if the battery loses its power?</u></b><br />When there is power cut, the required power is taken from the battery. Therefore the battery keeps losing its capacity. If the power supply comes back before the battery is depleted then the battery charger will start recharging, but if the power supply doesn't come back then the battery keeps supplying until it totally drains out. When the battery drains below a certain level the UPS sounds an alarm for your to shut down your computer and turn off the UPS. Some UPS' even have a built in system that shuts your computer down for you after a certain amount of UPS uptime.<br />
<b></b> <br />
<b><u>How long can the UPS provide power when there is a blackout?</u></b><br />This all depends on the specifications of the UPS and the requirement of the computer. A 600vA UPS for example can supply power to a computer with a 550W power supply for about 10 minutes or more.<br />
<b></b> <br />
<b><u>Tips for buying an UPS</u></b><br />The backup time of your UPS is the most important you need to consider. Other than that, you should know how many KVA (Kilo Volt Ampere) your UPS has. A computer needs atleast 0.5 KVA (500VA) to function. If you are planning to connect more than one computer to a single UPS then you need to get one with a higher KVA.<br />
<b></b> <br />
<b><u>What type of battery does a UPS use?</u></b><br />UPS uses <b>SMF</b> batteries (Sealed Maintenance Free). These type of batteries can be used for 5 to 7 years continuously.
Would that be an LED (Light Emitting Diode), blinking on the back of the Power Supply?
If so, instead of being an LED that indicates the Power Supply has power to it, it has now turned into a diagnostic LED (Light), and is telling you the Power Supply is bad.
Do you have an economical multimeter, so I can guide you in testing the 3 low DC Voltages; that come out of the Power Supply? An economical multimeter can be purchased for as little as $5 to $12. I have seen them on checkout aisle racks, in major discount stores.
The dangerous high AC voltage, is kept contained within the metal case of the Power Supply. (100 to 240 Volts depending on what country you are in)
The Power Supply is a Converter. It converts the high AC voltage into 3 low DC Voltages; 3.3 Volts, 5 Volts, and 12 Volts. In comparison two D cell flashlight batteries produce 3 Volts DC.
OR; Use a KNOWN to be good, Compatible power supply; for a temporary test unit.
{"Honey, I'm going to borrow the Power Supply out of your computer. I'll put it back when I'm done." "What? I'll be sleeping on the couch? K"} (Lol!)
Also, is the inside of the computer dirty? (Computer Unplugged from power, Anti-Static Procedures FOLLOWED)
Let's start here......
Also, what is the Product Number? Back of computer tower, white Service Tag. P/N = Product Number
Check the fuse. Otherwise there's another fuse at the low voltage transformer itself. it will be covered with plastic tape on the primary winding of the transformer. Just replace it and enjoy your music
Hello Dear Specialists I have a problem with the APC Smart-UPS smart 1000VA: when I insert the power plug in the wall outlet in one ups , indicate the AVR Boost ups regulating low AC voltage, when I measuring the AC city power voltage that is 207v .whey this ups is not working about the AC low voltage? ,but it should be work from (170v ~ 230v) AC input volte.please solve this problem, which element of AVR from the ups is failed or wrong and give me free circuit diagram low & high AVR and charger and inverter circuits. thanks allot
If your outside condenser has a locked rotor or short circuit, than the unit WILL trip the breaker - as it should. On the other hand if a breaker is tripped a few times it will have less of a capacity that the rating, (this is designed in it). You will need to determine if the unit is locked (and broken) or the breaker has become too sensitive.
That's the range I wanted to know, thanks a lot. I want to know too that, is there any way to make it working around 130volts? as voltage stabilizer is working nicely!
