Voltage Stabilizer for LG 1.5 ton window type ac

I'm using LG 1.5 ton window type ac. my line voltage/current seems to be not enough for its optimum performance. for some time it blows normal air only and for some time it blows cool air and thus certainly it cannot make the room eough cool. this happens mostly in peak hours.
how to solve this problem? should i use a voltage stabilizer? if yes, then what should be its rating (KVA). my ac's input power rating is 1950 watt and its running current rating is 9.5 amp.
is there any calculation to find out KVA or VA rating of stabilizer for air conditioner of any capacity?

You should have around 120-125 volts at the outlet. If you have less than 110 volts at that one outlet, you may need to have your house wiring checked. Go ahead and call your local power company and have the power coming into your house checked at their transformer. They should do this at no charge to you.

Where can I buy Servo Stabilizer and Servo Voltage Stabilizer in india?


Servo stabilizer can save your high price machinery from voltage fluctuations, it works to maintain the voltage and supply the power to machinery constant. There are 2 types, one is Natural Air Cooled Oil Filled Servo Stabilizer and Natural Air Cooled Servo Voltage Stabilizer. Apex power Systems is a branded company for Servo Stabilizer. They are the manufacturer in Noida and supplying to pan India. If you have required a servo stabilizer for your plant, you can purchase it from Apex power systems. They are reliable.

What is the minimum volts required to run 1.5 ton 5 star AC?


Low voltage will burn out all the motors Higher currents will ruin the start capacitor on the compressor and fan motors too. 220 vac is the minimum. You have to allow for inrush or start up current which most likely is the cause of the under voltage. You'll have to get a larger capacity stabilizer.

DC to AC power cord Do they still make them if so under what name or product name?


"DC to AC" cords are not really a common item. They are called "Inverters". Typical inverters are 12VDC to 120VAC and are found in mobile applications to operate houshold current type (120VAC) devices. Inverters cost many times more than thier "AC to DC" or "AC to AC" sisters.

An "AC to DC" and "AC to AC" cord however, is a very common item. They are usually called simply "AC Adapters" and are sold in many electronics stores (Best Buy, Fry's, etc.) and electronic specialty stores (Radio Shack) and electrnics suppliers (MCM, etc.) Nearly all of them are designed to reduce the voltage in your home (120 VAC volts alternating current) to a different but usually lower voltage that is either AC or DC.

In order to select the proper AC adapter, you need to know:
(1) Input Voltage - this is the outlet voltage - often 120 volts in N. America, (2) Output voltage - this is the voltage the device needs and is often indicated near the jack, The adapted must match this voltage. (3) the device voltage type - this will be either AC or DC. The adapter must match the type as they are NOT interchangeable. (4) the size and type plug on the cord that will allow it to mate properly with the jack. There are many, many types and it should be tested for fit prior to plugging in and must match the device jack (5) the power requirements - this is usually shown as a number in Watts (w) and / or Amps (a). It is very important that the apdapter power rating is equal to or greater than the amount specified by the device. Failure to meet the requirements above can cause failure of the device, adapter or both.

I hope this helps and good luck!

My LG Split 1 ton Continue poor working with under voltage 180V (Due to Long distance Transformer), Once its capacitor have to change this summer. Now i arrange Stabilizer which give 230V. Before...


Unfortunately, there is not a great deal of information about LG splits available, but is you are talking $12,000 to to repair, then it is much cheaper to replace since a two ton complete is less that half that amount.

I have new Samsung 1.5 Ton Window AC ( around one month old). Whenever AC is switched on in FAN or Cool mode the AC (probably FAn motor) make irritating Humming Noise. The noise slightly reduces after...


It is possible that your AC is not getting the right voltage or frequency and hence is trying to scavenge in gettting the current. It will be good if you can check on the mains voltage or on the wiring for a good 15 amp supply line. If there is any reduction or load onthe wire then the voltage can drop considerably. So in the first place kindly check this out. If this seems in order you will have to check for the fan or the compressor motor to be humming. If your cooling seems fine then you can check on the capacitor of the fan or the starter motor. I am sure since this is in warranty you must make a claim to get a free replacement. Hope you find my advice useful Good day

My 1.5 ton,LG split AC shuts off rather


Hello
First the foam insulation is not just for looks,you will have some loss of cooling on the unit,the larger cooper line needs to be insulated,the small one does not.The large line is the suction line,the small one the liquid line.
Voltage,168 is low,sounds like a 208 volt unit or 220 volt.running at 168 or 198 ac volts is going to raise the amperage causing the compressor to run hot and work harder and soon burn up,And cause it to trip the breaker or shut itsself down on high heat.Your going to need to get that voltage fixed.I dont know why it needs a stabilizer if the unit was sized correctly it shouldnt need one.
Hope this helps.

LG DVD PLAYER THE INSIDE FUSE KEEPS BLOWING IVE BOUGHT THE SAME FUSES BUT STILL HAVE THE SAME PROBLEM


1. THERE SHOULD BE A SHORT CIRCUIT SOMEWHERE
2. THE WATTAGE YOUR DVD PLAYER IS CONNECTED TO IS HIGH
3. THE FUSE RATING IS LESS THAN REQUIRED OR NEEDED
4. YOUR HOME VOLTAGE IS LOW


5. SOLUTION, TRY USE A VOLTAGE STABILIZER BETWEEN YOUR SOCKET/POWER OUTLET AND YOUR DVD UNIT.
THIS SHOULD SOLVE ISSUES RELATED TO VOLTAGE OR CURRENT.

6. CHECK THE NAME PLATE FOR YOUR LG DVD PLAYER OR MAINTENANCE MANUAL FOR APPROPRIATE FUSE RATING AND CORRECT IF WRONG.

7. CHECK FOR ANY ABLE BRIDGING OR ANY METAL (EVEN IF IT IS A STRAND) CONTACTING TWO CIRCUITS TOGETHER.

8. CHECK MAYBE THE MOTOR DRIVING THE LASER HEAD IS BAD. COULD CAUSE THE FUSE TO BLOW DUE TO EXCESSIVE CURRENT AND INABILITY TO ROTATE.

My ac circuit breaker keep tripping


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.
