What things to consider while buying a Stabilizer for Air Conditioner – Buying Guide
Choosing the best stabilizer for your ac is a tough and confusing process. However, you cannot just let your air conditioner get damaged by any voltage fluctuations. So, if you are in search of a voltage stabilizer, our guide is going to help you for sure. We are going to take you through the process of selecting one.
Indicators
Technology has gone one step ahead to make the functioning easy for users. LED indicators is one such provision. You can view the input and output voltage. So how does this help? You can monitor the performance of the stabilizer and your air conditioner.
Most importantly, you can keep a track on the voltage fluctuation level. All the above listed voltage stabilizers have LED indicators. This is a basic feature. Before the LED indicators were invented, one could understand the performance by keeping a check on the arrow of the indicators. These were called galvanometer indicators.
Working range
The working range of the stabilizer is one of the most important aspects to look into. If the working range of the stabilizer is 150 – 260V, then the stabilizer will stop its functioning if the voltage goes more than 260V or less than 150V. If the voltage is within the range then the stabilizer will function and ensure the input voltage is stabilized and set it as per the required range of output voltage.
Mounting
A voltage stabilizer, being an electrical appliance, has a certain level of risk involved in it too. If you place the stabilizer on a flat surface, there are chances of it getting damaged. So, we would recommend you to invest in a stabilizer which is wall mountable. You can place it at a high level and this will protect your stabilizer to a certain extent. This will eliminate risk of shocks for you and your family.
Time Delay
Just like your refrigerator, your air conditioner also has a compressor. The compressor gets locked up if it gets disturbed by a power failure. If this happens then the motor consumes a strong current which will cause the compressor to get heated up. This can also cause the compressor to trip. However, the time delay feature can solve this problem. Voltage stabilizers with the time delay feature will ensure the compressor does not switch on immediately and gives it time to come out of this lock period.
Digitized
Most new voltage stabilizer models are digitized. These models are compatible with most devices. You can easily shift your stabilizer from one device to the other. It can also conveniently be connected with a generator.
Overload protection
Modern voltage stabilizers come with the overload protection technology. So, in this mechanism, the stabilizer stops its functioning incase of any overloading or short circuit. This will protect your air conditioner from burning out.
Surge protection
Surge protection is also known as spike guards. In case of any short circuit there can be voltage fluctuations. If this happens then the surge protection feature ensures supply of current, which is connected to the stabilizer, is stopped immediately. So, you can be sure of your appliance not getting damaged. Everest EWD 400-D Voltage Stabilizer for AC is equipped with the spike protection.
Budget
Budget plays a crucial role in influencing any buying decision. Voltage stabilizers are not a big investment. So, you should not be concerned about this aspect. Microtek EM4170 + Automatic Voltage Stabilizer for AC is the most economical option amongst all of the above.
Warranty
Most brands do come with a warranty period of 3-5 years. So, make sure you buy a voltage stabilizer with a maximum warranty period to ensure maximum protection to your air conditioner.
Benefits of Using Voltage Stabilizer with an Air Conditioner
A voltage stabilizer has now become a necessity for each household. Let’s tell you the benefits of using a voltage stabilizer with an air conditioner.
- It is a constant power supply to your air conditioner.
- It will protect your ac from damage due to overload protection.
- A voltage stabilizer will cost you less in comparison to the damage caused to the appliance.
- It can regulate the AC power distribution line.
- The life of your air conditioner will get elongated.
- It will protect the ac from current spikes, distorted waveforms, voltage surges, impulsive noise etc.
- It is low on maintenance.
- The stabilizer will increase the efficiency of your air conditioner.
- It reduced the level of the risk factor.
How should you decide which stabilizer works best for your AC?
Selecting the right stabilizer for your air conditioner is a little technical. It should depend based upon the energy consumption of the air conditioner and the voltage fluctuations in your area. You should be aware about the rating of the appliance which is usually mentioned as KW, KVA or AMPS. You should also be aware of the nominal line frequency and voltage.
How should you select a stabilizer?
- The power rating, current and the voltage of the appliance should be checked. This should be mentioned in the user manual or on the specification sticker.
- The standard service voltage should be 230VAC, 50 Hz.
- For maximum power, multiply ‘230 by the max current rate. Make sure you add a 20-25% safety margin to the rating of the stabilizer. You may have some buffer if you plan on adding some more devices later.
- The surge current should also be considered. This current flow once you turn on the device.
- Since the voltage stabilizer is rating in watts, you may assume a power factor of 0.8 (W+V*A*pf).
Some important points to remember:
- Be sure you are aware of the nature of the load which you would connect to the voltage stabilizer.
- Ensure to note down the power (of all the appliances) in watts.
- The total energy consumption of all the connected appliances will give you the load on the stabilizer in watts.
- Most stabilizers are measured in VA (volt ampere).
- For the actual reading in VA from watts, some detailed measurements will have to be taken.
- You can have a rough approximation by increasing the watts by 20%. This will give you an approximate VA size.
